| 1 | Design and fabrication of broadband ultralow reflectivity black Si surfaces by laser micro/nanoprocessing显示文摘Light collection efficiency is an important factor that affects the performance of many optical and optoelectronic devices.In these devices,the high reflectivity of interfaces can hinder efficient light collection.To minimize unwanted reflection,anti-reflection surfaces can be fabricated by micro/nanopatterning.In this paper,we investigate the fabrication of broadband anti-reflection Si surfaces by laser micro/nanoprocessing.Laser direct writing is applied to create microstructures on Si surfaces that reduce light reflection by light trapping.In addition,laser interference lithography and metal assisted chemical etching are adopted to fabricate the Si nanowire arrays.The anti-reflection performance is greatly improved by the high aspect ratio subwavelength structures,which create gradients of refractive index from the ambient air to the substrate.Furthermore,by decoration of the Si nanowires with metallic nanoparticles,surface plasmon resonance can be used to further control the broadband reflections,reducing the reflection to below 1.0%across from 300 to 1200 nm.An average reflection of 0.8%is achieved. | Jing Yang Fangfang Luo Tsung Sheng Kao Xiong Li Ghim Wei Ho Jinghua Teng Xiangang Luo Minghui Hong | 2014 | Light(Science & Applications)2014，3，1： | 17 |

| 3 | Off-axis multi-wavelength dispersion controllingmetalens for multi-color imaging显示文摘Dispersion control is crucial in optical systems,and chromatic aberration is an important factor affecting imaging quality in imaging systems.Due to the inherent property of materials,dispersion engineering is complex and needs to trade off other aberration in traditional ways.Although metasurface offers an effective method to overcome these limits and results in well-engineered dispersion,off-axis dispersion control is still a challenging topic.In this paper,we design a single-layer metalens which is capable of focusing at three wavelengths(473 nm,532 nm,and 632 nm)with different incident angles(0°,-17°and 17°)into the same point.We also demonstrate that this metalens can provide an alternative for the bulky color synthetic prism in a 3-chips digital micromirror device(DMD)laser projection system.Through this approach,various off-axis dispersion controlling optical devices could be realized. | Kaihua Dou Xin Xie Mingbo Pu Xiong Li Xiaoliang Ma Changtao Wang Xiangang Luo | 2020 | Opto-Electronic Advances2020，3，4： | 7 |
| 4 | Crosstalk-free achromatic full Stokes imaging polarimetry metasurface enabled by polarization-dependent phase optimization显示文摘Imaging polarimetry is one of the most widely used analytical technologies for object detection and analysis.To date,most metasurface-based polarimetry techniques are severely limited by narrow operating bandwidths and inevitable crosstalk,leading to detrimental effects on imaging quality and measurement accuracy.Here,we propose a crosstalkfree broadband achromatic full Stokes imaging polarimeter consisting of polarization-sensitive dielectric metalenses,implemented by the principle of polarization-dependent phase optimization.Compared with the single-polarization optimization method,the average crosstalk has been reduced over three times under incident light with arbitrary polarization ranging from 9μm to 12μm,which guarantees the measurement of the polarization state more precisely.The experimental results indicate that the designed polarization-sensitive metalenses can effectively eliminate the chromatic aberration with polarization selectivity and negligible crosstalk.The measured average relative errors are 7.08%,8.62%,7.15%,and 7.59%at 9.3,9.6,10.3,and 10.6μm,respectively.Simultaneously,the broadband full polarization imaging capability of the device is also verified.This work is expected to have potential applications in wavefront detection,remote sensing,light-field imaging,and so forth. | Yaxin Zhang Mingbo Pu Jinjin Jin Xinjian Lu Yinghui Guo Jixiang Cai Fei Zhang Yingli Ha Qiong He Mingfeng Xu Xiong Li Xiaoliang Ma Xiangang Luo | 2022 | Opto-Electronic Advances2022，5，11： | 6 |
| 5 | A draft sequence of the rice (Oryza sativa ssp. indica) genome显示文摘The sequence of the rice genome holds fundamental information for its biology, including physiology, genetics, development, and evolution, as well as information on many beneficial phenotypes of economic significance. Using a 'whole genome shotgun' approach, we have pro-duced a draft rice genome sequence of Oryza sativa ssp. in-dica, the major crop rice subspecies in China and many other regions of Asia. The draft genome sequence is constructed from over 4.3 million successful sequencing traces with an accumulative total length of 2214.9 Mb. The initial assembly of the non-redundant sequences reached 409.76 Mb in length, based on 3.30 million successful sequencing traces with a total length of 1797.4 Mb from an indica variant cultivar 93-11, giving an estimated coverage of 95.29% of the rice genome with an average base accuracy of higher than 99%.

| 6 | All‐metallic wide‐angle metasurfaces for multifunctional polarization manipulation显示文摘Optical camouflage is a magical capability of animals as first noticed in 1794 by Erasmus Darwin in Zoonomia,but current biomimetic camouflage strategies cannot be readily applied in complex environments involving multispectral and in particular multi-polarization detection.Here we develop a plasmonic approach toward broadband infrared polarimetric crypsis,where the polarized thermal emission near the pseudo-Brewster angle is the main signal source and no existing polarizing camouflage technique has been discovered in nature.Based on all-metallic subwavelength structures,an electrodynamic resistance-reduction mechanism is proposed to avoid the significant polarization-dependent infrared absorption/radiation.It is also found that the structured metal surface presents giant extrinsic anisotropy regarding the phase shift between orthogonal polarization states,which helps to realize ultrahigh-efficiency and tunable polarization conversion in an unprecedented manner.Finally,we note that the catenary optical theory may provide a useful means to explain and predict these unusual performances. | Xiaoliang Ma Mingbo Pu Xiong Li Yinghui Guo Xiangang Luo | 2019 | Opto-Electronic Advances2019，2，3： | 6 |
| 7 | Molecular characteristics and evolutionary analysis of a very virulent infectious bursal disease virus显示文摘Infectious bursal disease virus(IBDV) poses a significant threat to the poultry industry. Viral protein 2(VP2), the major structural protein of IBDV, has been subjected to frequent mutations that have imparted tremendous genetic diversity to the virus. To determine how amino acid mutations may affect the virulence of IBDV, we built a structural model of VP2 of a very virulent strain of IBDV identified in China, vv IBDV Gx, and performed a molecular dynamics simulation of the interaction between virulence sites. The study showed that the amino acid substitutions that distinguish vv IBDV from attenuated IBDV(H253Q and T284A) favor a hydrophobic and flexible conformation of ?-barrel loops in VP2, which could promote interactions between the virus and potential IBDV-specific receptors. Population sequence analysis revealed that the IBDV strains prevalent in East Asia show a significant signal of positive selection at virulence sites 253 and 284. In addition, a signal of co-evolution between sites 253 and 284 was identified. These results suggest that changes in the virulence of IBDV may result from both the interaction and the co-evolution of multiple amino acid substitutions at virulence sites. | LI Zan QI XiaoLe REN XianGang CUI Lei WANG XiaoMei ZHU Ping | 2015 | Science China(Life Sciences)2015，58，8： | 6 |
| 8 | Tunable near-infrared plasmonic perfect absorber based on phase-change materials显示文摘A tunable plasmonic perfect absorber with a tuning range of 650 nm is realized by introducing a 20 nm thick phase-change material Ge2Sb2Te5 layer into the metal–dielectric–metal configuration.The absorption at the plasmonic resonance is kept above 0.96 across the whole tuning range.In this work we study this extraordinary optical response numerically and reveal the geometric conditions which support this phenomenon.This work shows a promising route to achieve tunable plasmonic devices for multi-band optical modulation,communication,and thermal imaging. | Yiguo Chen Xiong Li Xiangang Luo Stefan AMaier Minghui Hong | 2015 | Photonics Research2015，3，3： | 5 |
| 9 | Fault activity characteristics in the northern margin of the Tibetan Plateau before the Menyuan Ms6.4 earthquake显示文摘Fault deformation characteristics in the northern margin of the Tibetan Plateau before the Menyuan Ms6.4 earthquake are investigated through time-series and structural geological analysis based on cross-fault observation data from the Qilian Mountaine Haiyuan Fault belt and the West Qinling Fault belt. The results indicate: 1) Group short-term abnormal variations appeared in the Qilian Mountaine Haiyuan Fault belt and the West Qinling Fault belt before the Menyuan Ms6.4 earthquake. 2) More medium and short-term anomalies appear in the middle-eastern segment of the Qilian Mountain Fault belt and the West Qinling Fault belt, suggesting that the faults' activities are strong in these areas. The faults' activities in the middle-eastern segment of the Qilian Fault belt result from extensional stress, as before the earthquake, whereas those in the West Qinling Fault belt are mainly compressional. 3) In recent years, moderate-strong earthquakes occurred in both the Kunlun Mountain and the Qilian Mountain Fault belts, and some energy was released. It is possible that the seismicity moved eastward under this regime. Therefore, we should pay attention to the West Qinling Mountain area where an Ms6-7 earthquake could occur in future. | Dongzhuo Xu Chuanbao Zhu Xiangang Meng Yuan Li Qikai Sun Ke Zhang | 2016 | Geodesy and Geodynamics2016，7，4： | 5 |

| 12 | Tailoring active color rendering and multiband photodetection in a vanadium-dioxide-based metamaterial absorber显示文摘Metamaterials have demonstrated exotic electromagnetic properties, which offer a good platform for realizing light absorption, photodetection, filtering, and so on. However, broadband multifunctional metamaterial absorbers are restricted in cascaded structures. Here, broadband multifunctional properties were realized by introducing vanadium dioxide into a metamaterial absorber. Through the modified design and highly efficient utilization of multiple resonant modes, both plasmonic tunable color filters and near-infrared photodetectors can be simultaneously achieved by this construction. Meanwhile, active color and a photodetection band in the near-infrared range can become tunable with the insulating–metallic transition of vanadium dioxide. Thus, the variations of rendering colors could correspondingly indicate shifts of the near-infrared photodetection bands. This method theoretically confirms the feasibility of designing multifunctional devices via a vanadium-dioxide-based metamaterial absorber, which holds great promise for future versatile utilization of multiple physical mechanisms to achieve numerous functionalities in a simple nanostructure or device. | SHICHAO SONG XIAOLIANG MA MINGBO PU XIONG LI YINGHUI GUO PING GAO XIANGANG LUO | 2018 | Photonics Research2018，6，6： | 4 |

| 15 | Low-Angle Grain Boundaries in Sublimation Grown 6H-SiC Crystals显示文摘High-resolution X-ray diffractometry (HRXRD) was used to assess the quality of 6H-SiC crystals grown by sublimation method. The results show the occurrence of low-angle grain boundaries (LB) is close relative to the inclination of the crystal interface. At the central faceted region with 0° inclination the crystal is of high structural perfection. However, at the region close to the facet with less than 5° inclination LB occurs slightly and at the region close to the peripheral polytype ring with more than 5° inclination LB defect occurs heavily. The density of LB can be drastically reduced by decreasing radial temperature gradient that determines the shape of the crystal growth interface. | Jiang Shouzhen Li Xianxiang Dong Jie Chen Xiufang Xu Xiangang Hu Xiaobo | 2006 | Journal of Rare Earths2006，24，z1： | 3 |

| 17 | Dual-band and ultra-broadband photonic spin-orbit interaction for electromagnetic shaping based on single-layer silicon metasurfaces显示文摘Achieving electromagnetic wave scattering manipulation in the multispectral and broad operation band has been a long pursuit in stealth applications. Here, we present an approach by using single-layer metasurfaces composed of space-variant amorphous silicon ridges tiled on a metallic mirror, to generate high-efficiency dual-band and ultra-wideband photonic spin-orbit interaction and geometric phase. Two scattering engineered metasurfaces have been designed to reduce specular reflection;the first one can suppress both specular reflectances at 1.05–1.08 μm and 5–12 μm below 10%. The second one is designed for an ultra-broadband of 4.6–14 μm, which is actually implemented by cleverly connecting two bands of 4.6–6.1 μm and 6.1–14 μm. Furthermore, the presented structures exhibit low thermal emission at the same time due to the low absorption loss of silicon in the infrared spectrum, which can be regarded as an achievement of laser–infrared compatible camouflage.We believe the proposed strategy may open a new route to implement multispectral electromagnetic modulation and multiphysical engineering applications. | XIN XIE MINGBO PU XIONG LI KAIPENG LIU JINJIN JIN XIAOLIANG MA XIANGANG LUO | 2019 | Photonics Research2019，7，5： | 2 |

| 20 | Snapshot multi-dimensional computational imaging through a liquid crystal diffuser显示文摘Multi-dimensional optical imaging systems that simultaneously gather intensity,depth,polarimetric,and spectral information have numerous applications in medical sciences,robotics,and surveillance.Nevertheless,most current approaches require mechanical moving parts or multiple modulation processes and thus suffer from long acquisition time,high system complexity,or low sampling resolution.Here,a methodology to build snapshot multi-dimensional lensless imaging is proposed by combining planar-optics and computational technology,benefiting from sufficient flexibilities in optical engineering and robust information reconstructions.Specifically,a liquid crystal diffuser based on geometric phase modulation is designed to simultaneously encode the spatial,spectral,and polarization information of an object into a snapshot detected speckle pattern.At the same time,a post-processing algorithm acts as a special decoder to recover the hidden information in the speckle with the independent and unique point spread function related to the position,wavelength,and chirality.With the merits of snapshot acquisition,multi-dimensional perception ability,simple optical configuration,and compact device size,our approach can find broad potential applications in object recognition and classification. | YUNSONG LEI QI ZHANG YINGHUI GUO MINGBO PU FANG ZOU XIONG LI XIAOLIANG MA XIANGANG LUO | 2023 | Photonics Research2023，11，3： | 2 |
