| 1 | Generation of arbitrary vector vortex beams on hybrid-order Poincaré sphere显示文摘We propose theoretically and verify experimentally a method of combining a q-plate and a spiral phase plate to generate arbitrary vector vortex beams on a hybrid-order Poincaré sphere. We demonstrate that a vector vortex beam can be decomposed into a vector beam and a vortex, whereby the generation can be realized by sequentially using a q-plate and a spiral phase plate. The generated vector beam, vortex, and vector vortex beam are verified and show good agreement with the prediction. Another advantage that should be pointed out is that the spiral phase plate and q-plate are both fabricated on silica substrates, suggesting the potential possibility to integrate the two structures on a single plate. Based on a compact method of transmissive-type transformation, our scheme may have potential applications in future integrated optical devices. | Zhenxing Liu Yuanyuan Liu Yougang Ke Yachao Liu Weixing Shu Hailu Luo Shuangchun Wen | 2017 | Photonics Research2017，5，1： | 18 |
| 2 | Giant photonic spin Hall effect in momentum space in a structured metamaterial with spatially varying birefringence显示文摘The photonic spin Hall effect(SHE)in the reflection and refraction at an interface is very weak because of the weak spin-orbit interaction.Here,we report the observation of a giant photonic SHE in a dielectric-based metamaterial.The metamaterial is structured to create a coordinate-dependent,geometric Pancharatnam–Berry phase that results in an SHE with a spin-dependent splitting in momentum space.It is unlike the SHE that occurs in real space in the reflection and refraction at an interface,which results from the momentum-dependent gradient of the geometric Rytov–Vladimirskii–Berry phase.We theorize a unified description of the photonic SHE based on the two types of geometric phase gradient,and we experimentally measure the giant spin-dependent shift of the beam centroid produced by the metamaterial at a visible wavelength.Our results suggest that the structured metamaterial offers a potential method of manipulating spin-polarized photons and the orbital angular momentum of light and thus enables applications in spin-controlled nanophotonics. | Xiaohui Ling Xinxing Zhou Xunong Yi Weixing Shu Yachao Liu Shizhen Chen Hailu Luo Shuangchun Wen Dianyuan Fan | 2015 | Light(Science & Applications)2015，4，1： | 15 |
| 3 | Broadband ultrafast nonlinear optical response of few-layers graphene: toward the mid-infrared regime显示文摘Gapless linear energy dispersion of graphene endows it with unique nonlinear optical properties, including broadband nonlinear absorption and giant nonlinear refractive index. Herein, we experimentally observed that fewlayers graphene has obvious nonlinear absorption and large nonlinear refraction, as investigated by the Z-scan technique in the mid-infrared(mid-IR) regime. Our study may not only, for the first time to our knowledge, verify the giant nonlinear refractive index of graphene(~10-7cm2∕W) at the mid-IR, which is 7 orders of magnitude larger than other conventional bulk materials, but also provide some new insights for graphene-based mid-IR photonics,potentially leading to the emergence of several new conceptual mid-IR optoelectronics devices. | Lili Miao Yaqin Jiang Shunbin Lu Bingxin Shi Chujun Zhao Han Zhang Shuangchun Wen | 2015 | Photonics Research2015，3，5： | 7 |
| 4 | Two-dimensional optical spatial differentiation and high-contrast imaging显示文摘Optical analog signal processing technology has been widely studied and applied in a variety of science and engineering fields, with the advantages of overcoming the low-speed and high-power consumption associated with its digital counterparts. Much attention has been given to emerging metasurface technology in the field of optical imaging and processing systems. Here, we demonstrate, for the first time, broadband two-dimensional spatial differentiation and high-contrast edge imaging based on a dielectric metasurface across the whole visible spectrum. This edge detection method works for both intensity and phase objects simply by inserting the metasurface into a commercial optical microscope. This highly efficient metasurface performing a basic optical differentiation operation opens up new opportunities in applications of fast,compactible and power-efficient ultrathin devices for data processing and biological imaging. | Junxiao Zhou Haoliang Qian Junxiang Zhao Min Tang Qianyi Wu Ming Lei Hailu Luo Shuangchun Wen Shaochen Chen Zhaowei Liu | 2021 | National Science Review2021，8，6： | 6 |
| 5 | Ultrafast nonlinear absorption and nonlinear refraction in few-layer oxidized black phosphorus显示文摘We experimentally investigated the nonlinear optical response in few-layer oxidized black phosphorus(OBP) by the femtosecond Z-scan measurement technique, and found that OBP not only possesses strong ultrafast saturable absorption but also a nonlinear self-defocusing effect that is absent in black phosphorus(BP). The saturable absorption property originates mainly from the direct band structure, which is still maintained in OBP. The emergence of self-defocusing might originate from the combined consequences of the oxygen-induced defects in BP. Our experimental findings might constitute the first experimental evidence on how to dynamically tune its nonlinear property, offering an inroad in tailoring its optical properties through chemical modification(oxidation, introducing defects, etc.). The versatile ultrafast nonlinear optical properties(saturable absorption and self-defocusing) imply a significant potential of the layered OBP in the development of unprecedented optoelectronic devices, such as mode lockers, optical switches, laser beam shapers, and wavelength converters. | Shunbin Lu Yanqi Ge Zhengbo Sun Zongyu Huang Rui Cao Chujun Zhao Shuangchun Wen Dianyuan Fan Jianqing Li Han Zhang | 2016 | Photonics Research2016，4，6： | 5 |

| 7 | Potential applications of porous organic polymers as adsorbent for the adsorption of volatile organic compounds显示文摘Volatile organic compounds(VOCs)with high toxicity and carcinogenicity are emitted from kinds of industries,which endanger human health and the environment.Adsorption is a promising method for the treatment of VOCs due to its low cost and high efficiency.In recent years,activated carbons,zeolites,and mesoporous materials are widely used to remove VOCs because of their high specific surface area and abundant porosity.However,the hydrophilic nature and low desorption rate of those materials limit their commercial application.Furthermore,the adsorption capacities of VOCs still need to be improved.Porous organic polymers(POPs)with extremely high porosity,structural diversity,and hydrophobic have been considered as one of the most promising candidates for VOCs adsorption.This review generalized the superiority of POPs for VOCs adsorption compared to other porous materials and summarized the studies of VOCs adsorption on different types of POPs.Moreover,the mechanism of competitive adsorption between water and VOCs on the POPs was discussed.Finally,a concise outlook for utilizing POPs for VOCs adsorption was discussed,noting areas in which further work is needed to develop the next-generation POPs for practical applications. | Shuangchun Lu Qingling Liu Rui Han Miao Guo Jiaqi Shi Chunfeng Song Na Ji Xuebin Lu Degang Ma | 2021 | Journal of Environmental Sciences2021，33，7： | 4 |
| 8 | Photonic spin Hall effect on the surface of anisotropic two-dimensional atomic crystals显示文摘We examine the spin-orbit interaction of light and photonic spin Hall effect on the surface of anisotropic two-dimensional atomic crystals. As an example, the photonic spin Hall effect on the surface of black phosphorus is investigated. The photonic spin Hall effect manifests itself as the spin-dependent beam shifts in both transverse and in-plane directions. We demonstrate that the spin-dependent shifts are sensitive to the orientation of the optical axis, doping concentration, and interband transitions. These results can be extensively extended to other anisotropic two-dimensional atomic crystals. By incorporating the quantum weak measurement techniques, the photonic spin Hall effect holds great promise for detecting the parameters of anisotropic two-dimensional atomic crystals. | WENSHUAI ZHANG WEIJIE WU SHIZHEN CHEN JIN ZHANG XIAOHUI LING WEIXING SHU HAILU LUO SHUANGCHUN WEN | 2018 | Photonics Research2018，6，6： | 4 |

Here, we report the highly stable femtosecond pulse generation from a MXene mode-locked fiber laser. We have prepared the high-quality Ti_3C_2 T_x nanosheets via the etching method, and characterized their ultrafast dynamics and broadband nonlinear optical responses. The obvious intensity-and wavelength-dependent nonlinear responses have been observed and investigated. In addition, a highly stable femtosecond fiber laser with signal-to-noise ratio up to 70.7 dB and central wavelength of 1567.3 nm has been delivered. The study may provide some valuable design guidelines for the development of ultrafast, broadband nonlinear optical modulators, and open new avenues toward advanced photonic devices based on MXenes. | JIE LI ZILONG ZHANG LIN DU LILI MIAO JUN YI BIN HUANG YANHONG ZOU CHUJUN ZHAO SHUANGCHUN WEN | 2019 | Photonics Research2019，7，3： | 3 |

| 12 | Observation of tiny polarization rotation rate in total internal reflection via weak measurements显示文摘In this paper,we examine the tiny polarization rotation effect in total internal reflection due to the spin–orbit interaction of light.We find that the tiny polarization rotation rate will induce a geometric phase gradient,which can be regarded as the physical origin of photonic spin Hall effect.We demonstrate that the spin-dependent splitting in position space is related to the polarization rotation in momentum space,while the spin-dependent splitting in momentum space is attributed to the polarization rotation in position space.Furthermore,we introduce a quantum weak measurement to determine the tiny polarization rotation rate.The rotation rate in momentum space is obtained with 118 nm,which manifests itself as a spatial shift,and the rotation rate in position space is achieved with 38 μrad∕λ,which manifests itself as an angular shift.The investigation of the polarization rotation characteristics will provide insights into the photonic spin Hall effect and will enable us to better understand the spin–orbit interaction of light. | CHENGQUAN MI SHIZHEN CHEN XINXING ZHOU KAI TIAN HAILU LUO SHUANGCHUN WEN | 2017 | Photonics Research2017，5，2： | 2 |
| 13 | Flat multifunctional liquid crystal elements through multi-dimensional information multiplexing显示文摘Flat optical elements have attracted enormous attentions and act as promising candidates for the next generation of optical components.As one of the most outstanding representatives,liquid crystal(LC)has been widely applied in flat panel display industries and inspires the wavefront modulation with the development of LC alignment techniques.However,most LC elements perform only one type of optical manipulation and are difficult to realize the multifunctionality and light integration.Here,flat multifunctional liquid crystal elements(FMLCEs),merely composed of anisotropic LC molecules with space-variant orientations,are presented for multichannel information manipulation by means of polarization,space and wavelength multiplexing.Specifically,benefiting from the unique light response with the change of the incident polarization,observation plane,and working wavelength,a series of FMLCEs are demonstrated to achieve distinct near-and far-field display functions.The proposed strategy takes full advantage of basic optical parameters as the decrypted keys to improve the information capacity and security,and we expect it to find potential applications in information encryption,optical anti-counterfeiting,virtual/augmented reality,etc. | Dongliang Tang Zhenglong Shao Xin Xie Yingjie Zhou Xiaohu Zhang Fan Fan Shuangchun Wen | 2023 | Opto-Electronic Advances2023，6，4： | 2 |
| 14 | New three-dimensional guidance law for BTT missiles based on differential geometry and Lie-group显示文摘A new non-decoupling three-dimensional guidance law is proposed for bank-to-turn (BTT) missiles with the motion coupling problem.In this method,the different geometry is taken for theoretically modeling on BTT missiles' motion within the threedimensional style without information loss,and meanwhile,Liegroup is utilized to describe the line-of-sight (LOS) azimuth when the terminal angular constraints are considered.Under these circumstances,a guidance kinematics model is established based on differential geometry.Then,corresponding to no terminal angular constraint and terminal angular constraints,guidance laws are respectively designed by using proportional control and generalized proportional-derivative (PD) control in SO(3) group.Eventually,simulation results validate that this developed method can effectively avoid the complexity of pure Lie-group method and the information loss of the traditional decoupling method as well. | Shuangchun Peng Liang Pan Tianjiang Hu Lincheng Shen | 2011 | Journal of Systems Engineering and Electronics2011，22，4： | 2 |
| 15 | Photonic spin Hall effect:fundamentals and emergent applications显示文摘The photonic spin Hall effect(SHE)refers to the transverse spin separation of photons with opposite spin angular momentum,after the beam passes through an optical interface or inhomogeneous medium,manifested as the spin-dependent splitting.It can be considered as an analogue of the SHE in electronic systems:the light’s right-circularly polarized and left-circularly polarized components play the role of the spin-up and spin-down electrons,and the refractive index gradient replaces the electronic potential gradient.Remarkably,the photonic SHE originates from the spin-orbit interaction of the photons and is mainly attributed to two different geometric phases,i.e.,the spin-redirection Rytov-Vlasimirskii-Berry in momentum space and the Pancharatnam-Berry phase in Stokes parameter space.The unique properties of the photonic SHE and its powerful ability to manipulate the photon spin,gradually,make it a useful tool in precision metrology,analog optical computing and quantum imaging,etc.In this review,we provide a brief framework to describe the fundamentals and advances of photonic SHE,and give an overview on the emergent applications of this phenomenon in different scenes. | Shuoqing Liu Shizhen Chen Shuangchun Wen Hailu Luo | 2022 | Opto-Electronic Science2022，1，7： | 2 |
