| 1 | Fringe pattern analysis using deep learning显示文摘In many optical metrology techniques,fringe pattern analysis is the central algorithm for recovering the underlying phase distribution from the recorded fringe patterns.Despite extensive research efforts for decades,how to extract the desired phase information,with the highest possible accuracy,from the minimum number of fringe patterns remains one of the most challenging open problems.Inspired by recent successes of deep learning techniques for computer vision and other applications,we demonstrate for the first time,to our knowledge,that the deep neural networks can be trained to perform fringe analysis,which substantially enhances the accuracy of phase demodulation from a single fringe pattern.The effectiveness of the proposed method is experimentally verified using carrier fringe patterns under the scenario of fringe projection profilometry.Experimental results demonstrate its superior performance,in terms of high accuracy and edge-preserving,over two representative single-frame techniques:Fourier transform profilometry and windowed Fourier transform profilometry. | Shijie Feng Qian Chen Guohua Gu Tianyang Tao Liang Zhang Yan Hu Wei Yin Chao Zuo | 2019 | Advanced Photonics2019，1，2： | 31 |
| 2 | Learning-based lensless imaging through optically thick scattering media显示文摘The problem of imaging through thick scattering media is encountered in many disciplines of science,ranging from mesoscopic physics to astronomy.Photons become diffusive after propagating through a scattering medium with an optical thickness of over 10 times the scattering mean free path.As a result,no image but only noise-like patterns can be directly formed.We propose a hybrid neural network for computational imaging through such thick scattering media,demonstrating the reconstruction of image information from various targets hidden behind a white polystyrene slab of 3 mm in thickness or 13.4 times the scattering mean free path.We also demonstrate that the target image can be retrieved with acceptable quality from a very small fraction of its scattered pattern,suggesting that the speckle pattern produced in this way is highly redundant.This leads to a profound question of how the information of the target being encoded into the speckle is to be addressed in future studies. | Meng Lyu Hao Wang Guowei Li Shanshan Zheng Guohai Situ | 2019 | Advanced Photonics2019，1，3： | 28 |
| 3 | Photonic circuits written by femtosecond laser in glass:improved fabrication and recent progress in photonic devices显示文摘Integrated photonics is attracting considerable attention and has found many applications in both classical and quantum optics,fulfilling the requirements for the ever-growing complexity in modern optical experiments and big data communication.Femtosecond(fs)laser direct writing(FLDW)is an acknowledged technique for producing waveguides(WGs)in transparent glass that have been used to construct complex integrated photonic devices.FLDW possesses unique features,such as three-dimensional fabrication geometry,rapid prototyping,and single step fabrication,which are important for integrated communication devices and quantum photonic and astrophotonic technologies.To fully take advantage of FLDW,considerable efforts have been made to produce WGs over a large depth with low propagation loss,coupling loss,bend loss,and highly symmetrical mode field.We summarize the improved techniques as well as the mechanisms for writing high-performance WGs with controllable morphology of cross-section,highly symmetrical mode field,low loss,and high processing uniformity and efficiency,and discuss the recent progress of WGs in photonic integrated devices for communication,topological physics,quantum information processing,and astrophotonics.Prospective challenges and future research directions in this field are also pointed out. | Dezhi Tan Zhuo Wang Beibei Xu Jianrong Qiu | 2021 | Advanced Photonics2021，3，2： | 19 |
| 4 | Review of bio-optical imaging systems with a high space-bandwidth product显示文摘Optical imaging has served as a primary method to collect information about biosystems across scales—from functionalities of tissues to morphological structures of cells and even at biomolecular levels.However,to adequately characterize a complex biosystem,an imaging system with a number of resolvable points,referred to as a space-bandwidth product(SBP),in excess of one billion is typically needed.Since a gigapixel-scale far exceeds the capacity of current optical imagers,compromises must be made to obtain either a low spatial resolution or a narrow field-of-view(FOV).The problem originates from constituent refractive optics—the larger the aperture,the more challenging the correction of lens aberrations.Therefore,it is impractical for a conventional optical imaging system to achieve an SBP over hundreds of millions.To address this unmet need,a variety of high-SBP imagers have emerged over the past decade,enabling an unprecedented resolution and FOV beyond the limit of conventional optics.We provide a comprehensive survey of high-SBP imaging techniques,exploring their underlying principles and applications in bioimaging. | Jongchan Park David J.Brady Guoan Zheng Lei Tian Liang Gao | 2021 | Advanced Photonics2021，3，4： | 19 |
| 5 | Semiconductor nanolasers and the size-energyefficiency challenge:a review显示文摘Semiconductor lasers,an important subfield of semiconductor photonics,have fundamentally changed many aspects of our lives and enabled many technologies since their creation in the 1960s.As in other semiconductor-based fields,such as microelectronics,miniaturization has been a constant theme,with nanolasers being an important frontier of research over the last decade.We review the progress,existing issues,and future prospects of nanolasers,especially in relation to their potential application in chip-scale optical interconnects.One of the important challenges in this application is minimizing the size and energy consumption of nanolasers.We begin with the application background of this challenge and then compare basic features of various semiconductor lasers.We present existing issues with nanolasers and discuss potential solutions to meet the size and energy-efficiency challenge.Our discussions cover a broad range of miniaturized lasers,including plasmonic nanolasers and lasers with two-dimensional monolayer gain materials,with focus on near-infrared wavelengths. | Cun-Zheng Ning | 2019 | Advanced Photonics2019，1，1： | 17 |
| 6 | Nonlinear optics in all-dielectric nanoantennas and metasurfaces:a review显示文摘Free from phase-matching constraints,plasmonic metasurfaces have contributed significantly to the control of optical nonlinearity and enhancement of nonlinear generation efficiency by engineering subwavelength meta-atoms.However,high dissipative losses and inevitable thermal heating limit their applicability in nonlinear nanophotonics.All-dielectric metasurfaces,supporting both electric and magnetic Mie-type resonances in their nanostructures,have appeared as a promising alternative to nonlinear plasmonics.High-index dielectric nanostructures,allowing additional magnetic resonances,can induce magnetic nonlinear effects,which,along with electric nonlinearities,increase the nonlinear conversion efficiency.In addition,low dissipative losses and high damage thresholds provide an extra degree of freedom for operating at high pump intensities,resulting in a considerable enhancement of the nonlinear processes.We discuss the current state of the art in the intensely developing area of all-dielectric nonlinear nanostructures and metasurfaces,including the role of Mie modes,Fano resonances,and anapole moments for harmonic generation,wave mixing,and ultrafast optical switching.Furthermore,we review the recent progress in the nonlinear phase and wavefront control using all-dielectric metasurfaces.We discuss techniques to realize alldielectric metasurfaces for multifunctional applications and generation of second-order nonlinear processes from complementary metal–oxide–semiconductor-compatible materials. | Basudeb Sain Cedrik Meier Thomas Zentgraf | 2019 | Advanced Photonics2019，1，2： | 17 |
| 7 | Three-dimensional tomography of red blood cells using deep learning显示文摘We accurately reconstruct three-dimensional(3-D)refractive index(RI)distributions from highly ill-posed two-dimensional(2-D)measurements using a deep neural network(DNN).Strong distortions are introduced on reconstructions obtained by the Wolf transform inversion method due to the ill-posed measurements acquired from the limited numerical apertures(NAs)of the optical system.Despite the recent success of DNNs in solving ill-posed inverse problems,the application to 3-D optical imaging is particularly challenging due to the lack of the ground truth.We overcome this limitation by generating digital phantoms that serve as samples for the discrete dipole approximation(DDA)to generate multiple 2-D projection maps for a limited range of illumination angles.The presented samples are red blood cells(RBCs),which are highly affected by the ill-posed problems due to their morphology.The trained network using synthetic measurements from the digital phantoms successfully eliminates the introduced distortions.Most importantly,we obtain high fidelity reconstructions from experimentally recorded projections of real RBC sample using the network that was trained on digitally generated RBC phantoms.Finally,we confirm the reconstruction accuracy using the DDA to calculate the 2-D projections of the 3-D reconstructions and compare them to the experimentally recorded projections. | Joowon Lim Ahmed B.Ayoub Demetri Psaltis | 2020 | Advanced Photonics2020，2，2： | 13 |
| 8 | Optical trapping with structured light: a review显示文摘Optical trapping describes the interaction between light and matter to manipulate micro-objects through momentum transfer.In the case of 3D trapping with a single beam,this is termed optical tweezers.Optical tweezers are a powerful and noninvasive tool for manipulating small objects,and have become indispensable in many fields,including physics,biology,soft condensed matter,among others.In the early days,optical trapping was typically accomplished with a single Gaussian beam.In recent years,we have witnessed rapid progress in the use of structured light beams with customized phase,amplitude,and polarization in optical trapping.Unusual beam properties,such as phase singularities on-axis and propagation invariant nature,have opened up novel capabilities to the study of micromanipulation in liquid,air,and vacuum.We summarize the recent advances in the field of optical trapping using structured light beams. | Yuanjie Yang Yu-Xuan Ren Mingzhou Chen Yoshihiko Arita Carmelo Rosales-Guzmán | 2021 | Advanced Photonics2021，3，3： | 12 |
| 9 | Multifunctional integration on optical fiber tips: challenges and opportunities显示文摘.The flat endface of an optical fiber tip is an emerging light-coupled microscopic platform that combines fiber optics with planar micro-and nanotechnologies.Since different materials and structures are integrated onto the endfaces,optical fiber tip devices have miniature sizes,diverse integrated functions,and low insertion losses,making them suitable for all-optical networks.In recent decades,the increasing demand for multifunctional optical fibers has created opportunities to develop various structures on fiber tips.Meanwhile,the unconventional shape of optical fibers presents challenges involving the adaptation of standard planar micro-and nanostructure preparation strategies for fiber tips.In this context,researchers are committed to exploring and optimizing fiber tip manufacturing techniques,thereby paving the way for future integrated all-fiber devices with multifunctional applications.First,we present a broad overview of current fabrication technologies,classified as“top-down,”“bottom-up,”and“material transfer”methods,for patterning optical fiber tips.Next,we review typical structures integrated on fiber tips and their known and potential applications,categorized with respect to functional structure configurations,including“optical functionalization”and“electrical integration.”Finally,we discuss the prospects for future opportunities involving multifunctional integrated fiber tips. | Yifeng Xiong Fei Xu | 2020 | Advanced Photonics2020，2，6： | 11 |
| 10 | Infrared upconversion imaging in nonlinear metasurfaces显示文摘Infrared imaging is a crucial technique in a multitude of applications,including night vision,autonomous vehicle navigation,optical tomography,and food quality control.Conventional infrared imaging technologies,however,require the use of materials such as narrow bandgap semiconductors,which are sensitive to thermal noise and often require cryogenic cooling.We demonstrate a compact all-optical alternative to perform infrared imaging in a metasurface composed of GaAs semiconductor nanoantennas,using a nonlinear wave-mixing process.We experimentally show the upconversion of short-wave infrared wavelengths via the coherent parametric process of sum-frequency generation.In this process,an infrared image of a target is mixed inside the metasurface with a strong pump beam,translating the image from the infrared to the visible in a nanoscale ultrathin imaging device.Our results open up new opportunities for the development of compact infrared imaging devices with applications in infrared vision and life sciences. | Rocio Camacho-Morales Davide Rocco Lei Xu Valerio Flavio Gili Nikolay Dimitrov Lyubomir Stoyanov Zhonghua Ma Andrei Komar Mykhaylo Lysevych Fouad Karouta Alexander Dreischuh Hark Hoe Tan Giuseppe Leo Costantino De Angelis Chennupati Jagadish Andrey E.Miroshnichenko Mohsen Rahmani Dragomir N.Neshev | 2021 | Advanced Photonics2021，3，3： | 11 |
| 11 | Engineering photonic angular momentum with structured light:a review显示文摘Structured light with inhomogeneous phase,amplitude,and polarization spatial distributions that represent an infinite-dimensional space of eigenstates for light as the ideal carrier can provide a structured combination of photonic spin and orbital angular momentum(OAM).Photonic spin angular momentum(SAM)interactions with matter have long been studied,whereas the photonic OAM has only recently been discovered,receiving attention in the past three decades.Although controlling polarization(i.e.,SAM)alone can provide useful information about the media with which the light interacts,light fields carrying both OAM and SAM may provide additional information,permitting new sensing mechanisms and light–matter interactions.We summarize recent developments in controlling photonic angular momentum(AM)using complex structured optical fields.Arbitrarily oriented photonic SAM and OAM states may be generated through careful engineering of the spatial and temporal structures of optical fields.Moreover,we discuss potential applications of specifically engineered photonic AM states in optical tweezers,directional coupling,and optical information transmission and processing. | Jian Chen Chenhao Wan Qiwen Zhan | 2021 | Advanced Photonics2021，3，6： | 11 |
| 12 | Advances in soliton microcomb generation显示文摘Optical frequency combs,a revolutionary light source characterized by discrete and equally spaced frequencies,are usually regarded as a cornerstone for advanced frequency metrology,precision spectroscopy,high-speed communication,distance ranging,molecule detection,and many others.Due to the rapid development of micro/nanofabrication technology,breakthroughs in the quality factor of microresonators enable ultrahigh energy buildup inside cavities,which gives birth to microcavity-based frequency combs.In particular,the full coherent spectrum of the soliton microcomb(SMC)provides a route to low-noise ultrashort pulses with a repetition rate over two orders of magnitude higher than that of traditional mode-locking approaches.This enables lower power consumption and cost for a wide range of applications.This review summarizes recent achievements in SMCs,including the basic theory and physical model,as well as experimental techniques for single-soliton generation and various extraordinary soliton states(soliton crystals,Stokes solitons,breathers,molecules,cavity solitons,and dark solitons),with a perspective on their potential applications and remaining challenges. | Weiqiang Wang Leiran Wang Wenfu Zhang | 2020 | Advanced Photonics2020，2，3： | 10 |
| 13 | End-to-end deep learning framework for digital holographic reconstruction显示文摘Digital holography records the entire wavefront of an object,including amplitude and phase.To reconstruct the object numerically,we can backpropagate the hologram with Fresnel–Kirchhoff integralbased algorithms such as the angular spectrum method and the convolution method.Although effective,these techniques require prior knowledge,such as the object distance,the incident angle between the two beams,and the source wavelength.Undesirable zero-order and twin images have to be removed by an additional filtering operation,which is usually manual and consumes more time in off-axis configuration.In addition,for phase imaging,the phase aberration has to be compensated,and subsequently an unwrapping step is needed to recover the true object thickness.The former either requires additional hardware or strong assumptions,whereas the phase unwrapping algorithms are often sensitive to noise and distortion.Furthermore,for a multisectional object,an all-in-focus image and depth map are desired for many applications,but current approaches tend to be computationally demanding.We propose an end-to-end deep learning framework,called a holographic reconstruction network,to tackle these holographic reconstruction problems.Through this data-driven approach,we show that it is possible to reconstruct a noise-free image that does not require any prior knowledge and can handle phase imaging as well as depth map generation. | Zhenbo Ren Zhimin Xu Edmund YLam | 2019 | Advanced Photonics2019，1，1： | 10 |
| 14 | Adaptive-sampling near-Doppler-limited terahertz dual-comb spectroscopy with a free-running single-cavity fiber laser显示文摘Dual-comb spectroscopy(DCS)is an emerging spectroscopic tool with the potential to simultaneously achieve a broad spectral coverage and ultrahigh spectral resolution with rapid data acquisition.However,the need for two independently stabilized ultrafast lasers significantly hampers the potential application of DCS.We demonstrate mode-resolved DCS in the THz region based on a free-running singlecavity dual-comb fiber laser with the adaptive sampling method.While the use of a free-running single-cavity dual-comb fiber laser eliminates the need for two mode-locked lasers and their frequency control,the adaptive sampling method strongly prevents the degradation of spectroscopic performance caused by the residual timing jitter in the free-running dual-comb laser.Doppler-limit-approaching absorption features with linewidths down to 25 MHz are investigated for low-pressure acetonitrile/air mixed gas by comb-mode-resolved THz spectroscopy.The successful demonstration clearly indicates its great potential for the realization of lowcomplexity,Doppler-limited THz spectroscopy instrumentation. | Jie Chen Kazuki Nitta Xin Zhao Takahiko Mizuno TakeoMinamikawa Francis Hindle Zheng Zheng Takeshi Yasui | 2020 | Advanced Photonics2020，2，3： | 9 |
| 15 | High-speed image reconstruction for optically sectioned,super-resolution structured illumination microscopy显示文摘Super-resolution structured illumination microscopy(SR-SIM)is an outstanding method for visualizing the subcellular dynamics in living cells.To date,by using elaborately designed systems and algorithms,SR-SIM can achieve rapid,optically sectioned,SR observation with hundreds to thousands of time points.However,real-time observation is still out of reach for most SIM setups as conventional algorithms for image reconstruction involve a heavy computing burden.To address this limitation,an accelerated reconstruction algorithm was developed by implementing a simplified workflow for SR-SIM,termed joint space and frequency reconstruction.This algorithm results in an 80-fold improvement in reconstruction speed relative to the widely used Wiener-SIM.Critically,the increased processing speed does not come at the expense of spatial resolution or sectioning capability,as demonstrated by live imaging of microtubule dynamics and mitochondrial tubulation. | Zhaojun Wang Tianyu Zhao Huiwen Hao Yanan Cai Kun Feng Xue Yun Yansheng Liang Shaowei Wang Yujie Sun Piero RBianco Kwangsung Oh Ming Lei | 2022 | Advanced Photonics2022，4，2： | 9 |
| 16 | Mode-locked 2.8-μm fluoride fiber laser:from soliton to breathing pulse显示文摘The mode-locked fluoride fiber laser(MLFFL)is an exciting platform for directly generating ultrashort pulses in the mid-infrared(mid-IR).However,owing to difficulty in managing the dispersion in fluoride fiber lasers,MLFFLs are restricted to the soliton regime,hindering pulse-energy scaling.We overcame the problem of dispersion management by utilizing the huge normal dispersion generated near the absorption edge of an infrared-bandgap semiconductor and promoted MLFFL from soliton to breathing-pulse mode-locking.In the breathing-pulse regime,the accumulated nonlinear phase shift can be significantly reduced in the cavity,and the pulse-energy-limitation effect is mitigated.The breathing-pulse MLFFL directly produced a pulse energy of 9.3 nJ and pulse duration of 215 fs,with a record peak power of 43.3 kW at 2.8μm.Our work paves the way for the pulse-energy and peak-power scaling of mid-IR fluoride fiber lasers,enabling a wide range of applications. | Zhipeng Qin Guoqiang Xie Hongan Gu Ting Hai Peng Yuan Jingui Ma Liejia Qian | 2019 | Advanced Photonics2019，1，6： | 9 |
| 17 | Revealing the behavior of soliton buildup in a mode-locked laser显示文摘Real-time spectroscopy based on an emerging time-stretch technique can map the spectral information of optical waves into the time domain,opening several fascinating explorations of nonlinear dynamics in mode-locked lasers.However,the self-starting process of mode-locked lasers is quite sensitive to environmental perturbation,which causes the transient behaviors of lasers to deviate from the true buildup process of solitons.We optimize the laser system to improve its stability,which suppresses the Q-switched lasing induced by environmental perturbation.We,therefore,demonstrate the first observation of the entire buildup process of solitons in a mode-locked laser,revealing two possible pathways to generate the temporal solitons.One pathway includes the dynamics of raised relaxation oscillation,quasimode-locking stage,spectral beating behavior,and finally the stable single-soliton mode-locking.The other pathway contains,however,an extra transient bound-state stage before the final single-pulse modelocking operation.Moreover,we propose a theoretical model to predict the buildup time of solitons,which agrees well with the experimental results.Our findings can bring real-time insights into ultrafast fiber laser design and optimization,as well as promote the application of fiber laser. | Xueming Liu Yudong Cui | 2019 | Advanced Photonics2019，1，1： | 9 |
| 18 | High-dimensional orbital angular momentum multiplexing nonlinear holography显示文摘Nonlinear holography has been identified as a vital platform for optical multiplexing holography because of the appearance of new optical frequencies.However,due to nonlinear wave coupling in nonlinear optical processes,the nonlinear harmonic field is coupled with the input field,laying a fundamental barrier to independent control of the interacting fields for holography.We propose and experimentally demonstrate high-dimensional orbital angular momentum(OAM)multiplexing nonlinear holography to overcome this problem.By dividing the wavefront of the fundamental wave into different orthogonal OAM channels,multiple OAM and polarization-dependent holographic images in both the fundamental wave and second-harmonic wave have been reconstructed independently in the spatial frequency domain through a type-II second harmonic generation process.Moreover,this method can be easily extended to cascadedχ2 nonlinear optical processes for multiplexing in more wavelength channels,leading to potential applications in multicasting in optical communications,multiwavelength display,multidimensional optical storage,anticounterfeiting,and optical encryption. | Xinyuan Fang Haocheng Yang Wenzhe Yao Tianxin Wang Yong Zhang Min Gu Min Xiaoa | 2021 | Advanced Photonics2021，3，1： | 8 |
| 19 | All-fiber ultrafast laser generating gigahertz-rate pulses based on a hybrid plasmonic microfiber resonator显示文摘Ultrafast lasers generating high-repetition-rate ultrashort pulses through various mode-locking methods can benefit many important applications,including communications,materials processing,astronomical observation,etc.For decades,mode-locking based on dissipative four-wave-mixing(DFWM)has been fundamental in producing pulses with repetition rates on the order of gigahertz(GHz),where multiwavelength comb filters and long nonlinear components are elemental.Recently,this method has been improved using filter-driven DFWM,which exploits both the filtering and nonlinear features of silica microring resonators.However,the fabrication complexity and coupling loss between waveguides and fibers are problematic.We demonstrate a tens-to hundreds-of gigahertz-stable pulsed all-fiber laser based on a hybrid plasmonic microfiber knot resonator device.Unlike previously reported pulse generation mechanisms,the operation utilizes the nonlinear-polarization-rotation(NPR)effect introduced by the polarization-dependent feature of the device to increase intracavity power for boosting DFWM mode-locking,which we term NPRstimulated DFWM.The easily fabricated versatile device acts as a polarizer,comb filter,and nonlinear component simultaneously,thereby introducing an application of microfiber resonator devices in ultrafast and nonlinear photonics.We believe that our work underpins a significant improvement in achieving practical low-cost ultrafast light sources. | Zi-xuan Ding Zi-nan Huang Ye Chen Cheng-bo Mou Yan-qing Lu Fei Xu | 2020 | Advanced Photonics2020，2，2： | 8 |
| 20 | Enhanced light-matter interactions in dielectric nanostructures via machine-learning approach显示文摘A key concept underlying the specific functionalities of metasurfaces is the use of constituent components to shape the wavefront of the light on demand.Metasurfaces are versatile,novel platforms for manipulating the scattering,color,phase,or intensity of light.Currently,one of the typical approaches for designing a metasurface is to optimize one or two variables among a vast number of fixed parameters,such as various materials’properties and coupling effects,as well as the geometrical parameters.Ideally,this would require multidimensional space optimization through direct numerical simulations.Recently,an alternative,popular approach allows for reducing the computational cost significantly based on a deep-learning-assisted method.We utilize a deep-learning approach for obtaining high-quality factor(high-Q)resonances with desired characteristics,such as linewidth,amplitude,and spectral position.We exploit such high-Q resonances for enhancedlight–matter interaction in nonlinearoptical metasurfaces and optomechanical vibrations,simultaneously.We demonstrate that optimized metasurfaces achieve up to 400-fold enhancement of the third-harmonic generation;at the same time,they also contribute to 100-fold enhancement of the amplitude of optomechanical vibrations.This approach can be further used to realize structures with unconventional scattering responses. | Lei Xu Mohsen Rahmani Yixuan Ma Daria ASmirnova Khosro Zangeneh Kamali Fu Deng Yan Kei Chiang Lujun Huang Haoyang Zhang Stephen Gould Dragomir N.Neshev Andrey E.Miroshnichenko | 2020 | Advanced Photonics2020，2，2： | 8 |
