| 1 | Interference-assisted kaleidoscopic meta-plexer for arbitrary spin-wavefront manipulation显示文摘Achieving simultaneous polarization and wavefront control,especially circular polarization with the auxiliary degree of freedom of light and spin angular momentum,is of fundamental importance in many optical applications.Interferences are typically undesirable in highly integrated photonic circuits and metasurfaces.Here,we propose an interference-assisted metasurface-multiplexer(meta-plexer)that counterintuitively exploits constructive and destructive interferences between hybrid meta-atoms and realizes independent spin-selective wavefront manipulation.Such kaleidoscopic meta-plexers are experimentally demonstrated via two types of single-layer spinwavefront multiplexers that are composed of spatially rotated anisotropic meta-atoms.One type generates a spinselective Bessel-beam wavefront for spin-down light and a low scattering cross-section for stealth for spin-up light.The other type demonstrates versatile control of the vortex wavefront,which is also characterized by the orbital angular momentum of light,with frequency-switchable numbers of beams under linearly polarized wave excitation.Our findings offer a distinct interference-assisted concept for realizing advanced multifunctional photonics with arbitrary and independent spin-wavefront features.A variety of applications can be readily anticipated in optical diodes,isolators,and spin-Hall meta-devices without cascading bulky optical elements. | He-Xiu Xu Guangwei Hu Ying Li Lei Han Jianlin Zhao Yunming Sun Fang Yuan Guang-Ming Wang Zhi Hao Jiang Xiaohui Ling Tie Jun Cui Cheng-Wei Qiu | 2019 | Light(Science & Applications)2019，8，1： | 11 |
| 2 | Full-space Cloud of Random Points with a Scrambling Metasurface显示文摘With the rapid progress in computer science,including artificial intelligence,big data and cloud computing,full-space spot generation can be pivotal to many practical applications,such as facial recognition,motion detection,augmented reality,etc.These opportunities may be achieved by using diffractive optical elements(DOEs)or light detection and ranging(LIDAR).However,DOEs suffer from intrinsic limitations,such as demanding depth-controlled fabrication techniques,large thicknesses(more than the wavelength),Lambertian operation only in half space,etc.LIDAR nevertheless relies on complex and bulky scanning systems,which hinders the miniaturization of the spot generator.Here,inspired by a Lambertian scatterer,we report a Hermitian-conjugate metasurface scrambling the incident light to a cloud of random points in full space with compressed information density,functioning in both transmission and reflection spaces.Over 4044 random spots are experimentally observed in the entire space,covering angles at nearly 90°.Our scrambling metasurface is made of amorphous silicon with a uniform subwavelength height,a nearly continuous phase coverage,a lightweight,flexible design,and low-heat dissipation.Thus,it may be mass produced by and integrated into existing semiconductor foundry designs.Our work opens important directions for emerging 3D recognition sensors,such as motion sensing,facial recognition,and other applications. | Zile Li Qi Dai Muhammad Q.Mehmood Guangwei Hu Boris Luk’yanchuk Jin Tao Chenglong Hao Inki Kim Heonyeong Jeong Guoxing Zheng Shaohua Yu Andrea Alù Junsuk Rho Cheng-Wei Qiu | 2018 | Light(Science & Applications)2018，7，1： | 6 |

| 4 | Structuring Nonlinear Wavefront Emitted from Monolayer Transition-Metal Dichalcogenides显示文摘The growing demand for tailored nonlinearity calls for a structure with unusual phase discontinuity that allows the realization of nonlinear optical chirality,holographic imaging,and nonlinear wavefront control.Transition-metal dichalcogenide(TMDC)monolayers offer giant optical nonlinearity within a few-angstrom thickness,but limitations in optical absorption and domain size impose restriction on wavefront control of nonlinear emissions using classical light sources.In contrast,noble metal-based plasmonic nanosieves support giant field enhancements and precise nonlinear phase control,with hundred-nanometer pixellevel resolution;however,they suffer from intrinsically weak nonlinear susceptibility.Here,we report a multifunctional nonlinear interface by integrating TMDC monolayers with plasmonic nanosieves,yielding drastically different nonlinear functionalities that cannot be accessed by either constituent.Such a hybrid nonlinear interface allows second-harmonic(SH)orbital angular momentum(OAM)generation,beam steering,versatile polarization control,and holograms,with an effective SH nonlinearityχ^((2))of~25 nm/V.This designer platform synergizes the TMDC monolayer and plasmonic nanosieves to empower tunable geometric phases and large field enhancement,paving the way toward multifunctional and ultracompact nonlinear optical devices. | Xuanmiao Hong Guangwei Hu Wenchao Zhao Kai Wang Shang Sun Rui Zhu Jing Wu Weiwei Liu Kian Ping Loh Andrew Thye Shen Wee Bing Wang Andrea Alù Cheng-Wei Qiu Peixiang Lu | 2020 | Research2020，，1： | 5 |
| 5 | Glucocorticoid receptor promotes the function of myeloid-derived suppressor cells by suppressing HIF1α-dependent glycolysis显示文摘Immunomodulatory signaling imposes tight regulations on metabolic programs within immune cells and consequentially determines immune response outcomes.Although the glucocorticoid receptor(GR)has been recently implicated in regulating the function of myeloid-derived suppressor cells(MDSCs),whether the dysregulation of GR in MDSCs is involved in immune-mediated hepatic diseases and how GR regulates the function of MDSCs in such a context remains unknown.Here,we revealed the dysregulation of GR expression in MDSCs during innate immunological hepatic injury(IMH)and found that GR regulates the function of MDSCs through modulating HIF1α-dependent glycolysis.Pharmacological modulation of GR by its agonist(dexamethasone,Dex)protects IMH mice against inflammatory injury.Mechanistically,GR signaling suppresses HIF1αand HIF1α-dependent glycolysis in MDSCs and thus promotes the immune suppressive activity of MDSCs.Our studies reveal a role of GR-HIF1αin regulating the metabolism and function of MDSCs and further implicate MDSC GR signaling as a potential therapeutic target in hepatic diseases that are driven by innate immune cell-mediated systemic inflammation. | Yun Lu Huanrong Liu Yujing Bi Hui Yang Yan Li Jian Wang Zhengguo Zhang Yu Wang Chunxiao Li Anna Jia Linian Han Ying Hu Yong Zhao Ruoning Wang Guangwei Liu | 2018 | Cellular & Molecular Immunology2018，15，6： | 4 |
| 6 | Arbitrary cylindrical vector beam generation enabled by polarization-selective Gouy phase shifter显示文摘Cylindrical vector beams(CVBs),which possess polarization distribution of rotational symmetry on the transverse plane,can be developed in many optical technologies.Conventional methods to generate CVBs contain redundant interferometers or need to switch among diverse elements,thus being inconvenient in applications containing multiple CVBs.Here we provide a passive polarization-selective device to substitute interferometers and simplify generation setup.It is accomplished by reversing topological charges of orbital angular momentum based on a polarization-selective Gouy phase.In the process,tunable input light is the only condition to generate a CVB with arbitrary topological charges.To cover both azimuthal and radial parameters of CVBs,we express the mapping between scalar Laguerre–Gaussian light on a basic Poincaré sphere and CVB on a high-order Poincaré sphere.The proposed device simplifies the generation of CVBs enormously and thus has potential in integrated devices for both quantum and classic optical experiments. | JUNLIANG JIA KEPENG ZHANG GUANGWEI HU MAPING HU TONG TONG QUANQUAN MU HONG GAO FULI LI CHENG-WEI QIU PEI ZHANG | 2021 | Photonics Research2021，9，6： | 4 |
| 7 | Hyperbolic metamaterials: fusing artificial structures to natural 2D materials显示文摘Optical metamaterials have presented an innovative method of manipulating light.Hyperbolic metamaterials have an extremely high anisotropy with a hyperbolic dispersion relation.They are able to support high-k modes and exhibit a high density of states which produce distinctive properties that have been exploited in various applications,such as super-resolution imaging,negative refraction,and enhanced emission control.Here,state-of-the-art hyperbolic metamaterials are reviewed,starting from the fundamental principles to applications of artificially structured hyperbolic media to suggest ways to fuse natural two-dimensional hyperbolic materials.The review concludes by indicating the current challenges and our vision for future applications of hyperbolic metamaterials. | Dasol Lee Sunae So Guangwei Hu Minkyung Kim Trevon Badloe Hanlyun Cho Jaekyung Kim Hongyoon Kim Cheng‑Wei Qiu Junsuk Rho | 2022 | eLight2022，2，1： | 3 |
| 8 | Phyllotaxis-inspired nanosieves with multiplexed orbital angular momentum显示文摘Nanophotonic platforms such as metasurfaces,achieving arbitrary phase profiles within ultrathin thickness,emerge as miniaturized,ultracompact and kaleidoscopic optical vortex generators.However,it is often required to segment or interleave independent sub-array metasurfaces to multiplex optical vortices in a single nano-device,which in turn affects the device’s compactness and channel capacity.Here,inspired by phyllotaxis patterns in pine cones and sunflowers,we theoretically prove and experimentally report that multiple optical vortices can be produced in a single compact phyllotaxis nanosieve,both in free space and on a chip,where one meta-atom may contribute to many vortices simultaneously.The time-resolved dynamics of on-chip interference wavefronts between multiple plasmonic vortices was revealed by ultrafast time-resolved photoemission electron microscopy.Our nature-inspired optical vortex generator would facilitate various vortex-related optical applications,including structured wavefront shaping,free-space and plasmonic vortices,and high-capacity information metaphotonics. | Zhongwei Jin David Janoschka Junhong Deng Lin Ge Pascal Dreher Bettina Frank Guangwei Hu Jincheng Ni Yuanjie Yang Jing Li Changyuan Yu Dangyuan Lei Guixin Li Shumin Xiao Shengtao Mei Harald Giessen Frank Meyer zu Heringdorf Cheng-Wei Qiu | 2021 | eLight2021，1，1： | 3 |

| 11 | Super-reflector enabled by non-interleaved spin-momentum-multiplexed metasurface显示文摘Electromagnetic wave multiplexing,especially for that occurring at different incidences(spatial-frequency multiplexing),is pivotal for ultrathin multifunctional interfaces and high-capacity information processing and communication.It is yet extremely challenging based on passive and compact wave elements,since the wave excitation and scattering channels are exclusively coupled through gradient phases and hence momentum matching condition at the interface.Here,we propose a spin-momentum multiplexed paradigm called a super-reflector enabling on-demand control of both retroreflections and anomalous reflections using a non-interleaved single-celled metasurface.By multiplexing four channels connecting two spin states excited onto each input of three spatial frequencies,a total of twelve channels are engineered,among which three are retroreflected channels and the residual are anomalous reflection ones.Our compound multiplexed super-reflector allows five degrees of freedom in circular polarization Jones'matrix,approaching the intrinsic upper limit of such planar metasurface.The concept has been experimentally verified by a proof-of-concept super-reflector at microwave frequency,showcasing twelve reflected beams and a high efficiency exceeding 90.6%defined as the ratio of reflected power to incidence for each channel beam.Our strategy opens a new avenue for angle multiplexing and angle-resolved metadevices toward the capacity limit of 2D planar Jones'matrix. | He-Xiu Xu Guangwei Hu Xianghong Kong Yanzhang Shao Patrice Genevet Cheng-Wei Qiu | 2023 | Light(Science & Applications)2023，12，4： | 2 |

| 15 | Investigation of the 6H-SiC (0001) surface by AFM显示文摘Micropipe and step structures on 6H-SiC (0001) surface were investigated by an atomic force microscopy (AFM). On the facet,all micropipes examined are the origins of spiral steps,indicating that dislocations intersect the surface at these points. Micro-pipes are empty-core super-dislocations as originally described by Frank. The micropipe radius increases with the square of the dis-location Burgers vector. From the center to the periphery,step structures change with different surface inclinations. Regular step is observed within the central faceted area. Step bunching and atomically rough surfaces are observed within the peripheral convex area. If the inclination with respect to the (0001) plane is large enough,step bunching of 15R-SiC can be observed. | Shouzhen Jiang Guangwei Yu Yingmin Wang Xiaobo Hu Xiangang Xu Minhua Jiang | 2008 | Journal of University of Science and Technology Beijing2008，15，5： | 1 |

| 18 | Damage Identification of General Overhead Travelling Crane Structure Based on Model Updating by Sensitivity显示文摘A model based damage identification was proposed by facilitating parameter sensitivity analysis and applied to a general overhead travelling crane.As updating reference data,experimental modal frequency was obtained by operational modal analysis(OMA)under ambient excitation.One dimensional damage function was defined to identify the damage by bending stiffness.The results showed that the model updating method could locate the damage and quantitatively describe the structure.The average error of eigenvalues between updated model analysis and the experimental results was less than 4% which proved the accuracy reliable.The comparison of finite element analysis and the test results of the deflection under the capacity load further verified the feasibility of this method. | Qing Guangwei Yue Lin Guo Qingtao Tao Yanhe Hu Jingbo | 2017 | Transactions of Nanjing University of Aeronautics and Astronautics2017，34，3： | 1 |
