| 1 | Facile metagrating holograms with broadband and extreme angle tolerance显示文摘The emerging meta-holograms rely on arrays of intractable meta-atoms with various geometries and sizes for customized phase profiles that can precisely modulate the phase of a wavefront at an optimal incident angle for given wavelengths.The stringent and band-limited angle tolerance remains a fundamental obstacle for their practical application,in addition to high fabrication precision demands.Utilizing a different design principle,we determined that facile metagrating holograms based on extraordinary optical diffraction can allow the molding of arbitrary wavefronts with extreme angle tolerances(near-grazing incidence)in the visible–near-infrared regime.By modulating the displacements between uniformly sized meta-atoms rather than the geometrical parameters,the metagratings produce a robust detour phase profile that is irrespective of the wavelength or incident angle.The demonstration of high-fidelity meta-holograms and in-site polarization multiplexing significantly simplifies the metasurface design and lowers the fabrication demand,thereby opening new routes for flat optics with high performances and improved practicality. | Zi-Lan Deng Junhong Deng Xin Zhuang Shuai Wang Tan Shi Guo Ping Wang Yao Wang Jian Xu Yaoyu Cao Xiaolei Wang Xing Cheng Guixin Li Xiangping Li | 2018 | Light(Science & Applications)2018，7，1： | 17 |
| 2 | Molecular characterization of Tomato yellow leaf curl China virus and its satellite DNA isolated from tobacco显示文摘Virus isolates, Y8, Y36 and Y38, were obtained from tobacco plants showing leaf curl symptoms in Honghe, Yunnan Province. In reactions with 14 monoclonal antibod-ies raised against Begomovirus particles, Y8, Y36 and Y38had similar antigenic reaction in TAS-ELISA as Tomato yel-low leaf curl China virus (TYLCCNV). The complete DNA-A nucleotide sequences of Y8, Y36 and Y38 were determinedand they contain 2727, 2730 and 2730 nucleotides, respec-tively. Each of the DNA-A sequences has a typical Bego-movirus genome organization encoding 6 ORFs with 2 ORFs [AV1(CP) and AV2] in virion-sense DNA and 4 ORFs (AC1to AC4) in complementary-sense DNA. Comparisons withtotal DNA-A, intergenic region and deduced amino acid se-quences of individual ORFs show that Y8, Y36 and Y38 are isolates of TYLCCNV. Satellite DNA molecules (DNAb) were found to be associated with Y8, Y36 and Y38, which consist of 1338, 1339 and 1338 nucleotides, respectively. Compari-sons show that these DNAb molecules share 98%—99% se-quence identities on nucleotide level and have a commonORF (designated C1) encoding 126 amino acids on the com-plementary strand. | XIE Yan, ZHOU Xueping & LI Guixin Institute of Biotechnology, Zhejiang University, Hangzhou 310029, China Correspondence should be addressed to Zhou Xueping (e-mail: zzhou@zju.edu.cn) | 2003 | Chinese Science Bulletin2003，48，8： | 13 |
| 3 | Metasurface interferometry toward quantum sensors显示文摘Optical metasurfaces open new avenues for the precise wavefront control of light for integrated quantum technology.Here,we demonstrate a hybrid integrated quantum photonic system that is capable of entangling and disentangling two-photon spin states at a dielectric metasurface.Via the interference of single-photon pairs at a nanostructured dielectric metasurface,a path-entangled two-photon NOON state with circular polarization that exhibits a quantum HOM interference visibility of 86±4% is generated.Furthermore,we demonstrate nonclassicality andphase sensitivity in a metasurface-based interferometer with a fringe visibility of 86.8±1.1%in the coincidence counts.This high visibility proves the metasurface-induced path entanglement inside the interferometer.Our findings provide a promising way to develop hybrid-integrated quantum technology operating in the high-dimensional mode space in various applications,such as imaging,sensing,and computing. | Philip Georgi Marcello Massaro Kai-Hong Luo Basudeb Sain Nicola Montaut Harald Herrmann Thomas Weiss Guixin Li Christine Silberhorn Thomas Zentgraf | 2019 | Light(Science & Applications)2019，8，1： | 7 |
| 4 | Identification of a novel DNA molecule associated with Tobacco leaf curl virus显示文摘A circular DNA molecule, designated as DNAp, was identified in tobacco plants infected with Tobacco leaf curl virus (TLCV) isolates Y5 and Y8 by PCR using primers based on the conserved region of the two reported DNAp sequences of whitefly-transmitted geminiviruses (WTGs). The complete nucleotide sequences of DNAβ of Y5 and Y8 (TLCV DNAβ) were determined. Y5 DNAβ comprises 1333 nucleotides encoding 8 predicted ORFs with 4 ORFs in virion-sense DNA and 4 ORFs in complementary-sense DNA; Y8 DNAP consists of 1338 nucleotides encoding 7 predicted ORFs with 4 ORFs in virion-sense DNA and 3 ORFs in complementary-sense DNA. TLCV DNAβhas little sequence homology to DNA-A of TLCV, except that it shares conserved TAATATTAC loop sequence with TLCV DNA-A. Sequence comparison showed that Y5 DNAβ shared 85% sequence homology with Y8 DNAβ, and both Y5 DNAβ and Y8 DNAβ had relatively low sequence identity (51%-65%) with the reported DNAβ molecules associated with Agera-tum yellow vein virus and Cotton leaf | XIE Yan ZHOU Xueping LI Zhenghe ZHANG Zhongkai LI Guixin | 2002 | Chinese Science Bulletin2002，47，15： | 6 |
| 5 | The pathogenicity on legumes of Cucumber mosaic virus was determined by 243 nucleotides on 2a polymerase gene of viral RNA2显示文摘We had isolated and identified two Cucumber mosaic virus (CMV) isolates, the CMV red bean (CMV-RB) isolate and the CMV pea (CMV-P1) isolate. CMV-RB induces necrotic local lesions on inoculated leaves of broad bean, pea, cowpea and bean, and could not infect these hosts systemically. However, CMV-P1 was able to infect these legumes systemically. To study the difference of pathogenic-ity on the legumes induced by these two CMV isolates, the full-length infectious cDNA clones of CMV-Fny, which induced similar symptoms as CMV-RB in the four legumes, were used. The 243 nucleotides fragment, which encodes highly conserved GDD amino acid motif on 2a replicase gene of CMV-Fny RNA2, was replaced with that of CMV-P1. The constructed chimeric virus FP could infect these legumes systemically. The exchange of this region changes the virus symptoms on the legumes, indicating that this 243 nucleotides fragment has major effect on pathogenicity of CMV on the legumes. | TAO Xiaorong ZHOU Xueping LI Guixin YU Jialin | 2002 | Chinese Science Bulletin2002，47，9： | 5 |
| 6 | A transcription factor STOP1-centered pathway coordinates ammonium and phosphate acquisition in Arabidopsis显示文摘Phosphorus(P)is an indispensable macronutrient required for plant growth and development.Natural phosphate(Pi)reserves are finite,and a better understanding of Pi utilization by crops is therefore vital for worldwide food security.Ammonium has long been known to enhance Pi acquisition efficiency in agriculture;however,the molecular mechanisms coordinating Pi nutrition and ammonium remains unclear.Here,we reveal that ammonium is a novel initiator that stimulates the accumulation of a key regulatory protein,STOP1,in the nuclei of Arabidopsis root cells under Pi deficiency.We show that Pi deficiency promotes ammonium uptake mediated by AMT1 transporters and causes rapid acidification of the root surface.Rhizosphere acidification-triggered STOP1 accumulation activates the excretion of organic acids,which help to solubilize Pi from insoluble iron or calcium phosphates.Ammonium uptake by AMT1 transporters is downregulated by a CIPK23 protein kinase whose expression is directly modulated by STOP1 when ammonium reaches toxic levels.Taken together,we have identified a STOP1-centered regulatory network that links external ammonium with efficient Pi acquisition from insoluble phosphate sources.These findings provide a framework for developing possible strategies to improve crop production by enhancing the utilization of non-bioavailable nutrients in soil. | Wen Hao Tian Jia Yuan Ye Meng Qi Cui Jun Bo Chang Yu Liu GuiXin Li Yun Rong Wu Ji Ming Xu Nicholas P.Harberd Chuan Zao Mao Chong Wei Jin Zhong Jie Ding Shao Jian Zheng | 2021 | Molecular Plant2021，14，9： | 5 |
| 7 | Gigantic electric-field-induced second harmonic generation from an organic conjugated polymer enhanced by a band-edge effect显示文摘Electric-field-induced second harmonic generation(EFISH),a third-order nonlinear process,arises from the interaction between the electric field of an external bias and that of two incident photons.EFISH can be used to dynamically control the nonlinear optical response of materials and is therefore promising for active nonlinear devices.However,it has been challenging to achieve a strong modulation with EFISH in conventional nonlinear materials.Here,we report a large tunability of an EFISH signal from a subwavelength-thick polymer film sandwiched between a transparent electrode and a metallic mirror.By exploiting the band-edge-enhanced third-order nonlinear susceptibility of the organic conjugated polymer,we successfully demonstrate a gigantic EFISH effect with a modulation ratio up to 422%V^(−1) at a pumping wavelength of 840 nm.The band-edge-enhanced EFISH opens new avenues for modulating the intensity of SHG signals and for controlling nonlinear electro-optic interactions in nanophotonic devices. | Shumei Chen King Fai Li Guixin Li Kok Wai Cheah Shuang Zhang | 2019 | Light(Science & Applications)2019，8，1： | 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 | Mass production of Li Fe PO_4/C energy materials using Fe–P waste slag显示文摘To effectively solve the agglomeration problems in the solid state reaction process,pre-adding glucose is adopted to the synthesis of Li Fe PO4/C energy materials using Fe–P waste slag. The average particle & grain size of Li FeP O4/C decreases,and the impurities in Li Fe PO4/C composites reduce to a great extent. It makes great sense to the mass industrial production. The optimum synthesis conditions determined in this work are based on the orthogonal experiments. The samples synthesized in a scale of 500 g exhibit high purity,excellent electrochemical performance,high reaction activity,good reversibility,and low polarization level.The discharge capacities are 145,134,117,and 102 m Ah/g at the current densities of 0.1 C,0.2 C,0.5 C and1 C,respectively. This work puts forward a practical suggestion for mass producing environmental benign and low cost Li FeP O4/C as cathode materials of lithium ion batteries. | Gen Li Pengcheng Wu Chunhui Luo Qian Cui Guixin Wang Kangping Yan | 2015 | Journal of Energy Chemistry2015，24，4： | 2 |
| 12 | Large-scale achromatic flat lens by light frequency-domain coherence optimization显示文摘Flat lenses,including metalens and diffractive lens,have attracted increasing attention due to their ability to miniaturize the imaging devices.However,realizing a large scale achromatic flat lens with high performance still remains a big challenge.Here,we developed a new framework in designing achromatic multi-level diffractive lenses by light coherence optimization,which enables the implementation of large-scale flat lenses under non-ideal conditions.As results,a series achromatic polymer lenses with diameter from 1 to 10mm are successfully designed and fabricated.The subsequent optical characterizations substantially validate our theoretical framework and show relatively good performance of the centimeter-scale achromatic multi-level diffractive lenses with a super broad bandwidth in optical wavelengths(400-1100 nm).After comparing with conventional refractive lens,this achromatic lens shows significant advantages in white-light imaging performance,implying a new strategy in developing practical planar optical devices. | Xingjian Xiao Yunwei Zhao Xin Ye Chen Chen Xinmou Lu Yansen Rong Junhong Deng Guixin Li Shining Zhu Tao Li | 2022 | Light(Science & Applications)2022，11，12： | 2 |

| 14 | Charge accumulation characteristic on polymer insulator surface under AC voltage in air and C_(4)F_(7)N/CO_(2)mixtures显示文摘Charge accumulation has always been a problem for the safe operation of gas insulated switchgear(GIS)/gas insulated transmission line(GIL)both under AC and DC.It is of great significance to investigate the behaviour of surface charge under high voltage.In this study,the charge distribution characteristics and accumulation mechanism on insulator surface in air and heptafluorobutyronitrile/carbon dioxide(C_(4)F_(7)N/CO_(2))mixtures under AC voltage are studied via the means of surface potential measurement and inversion algorithm,combined with the improved method of controlling the truncated phase of AC voltage.The results show that under the needle–plate electrode structure,charge distribution on the insulator surface presents a three-tier concentric circle structure both in air and C_(4)F_(7)N/CO_(2) gas mixtures,and the charge composition of the innermost circle is closely related to the truncated phase of AC voltage.Under the same amplitude of voltage,the range of charge distribution on insulator surface in C_(4)F_(7)N/CO_(2) mixtures is smaller than that in air,with the negative charges domination.It is suggested that the characteristic of charge distribution in C_(4)F_(7)N/CO_(2) mixtures is related to the larger electron attachment crosssection of C4F7N gas in a wide range of electron energy distribution. | Dayu Li Guixin Zhang Tianyu Wang Yicen Hou | 2020 | High Voltage2020，5，2： | 1 |

| 19 | Thermal energy dependent transient permittivity of epsilon-near-zero material显示文摘Transparent conductive oxides exhibit attractive optical nonlinearity with ultrafast response and giant refractive index change near the epsilon-near-zero(ENZ) wavelength, originating from the intraband dynamics of conduction electrons. The optical nonlinearity of ENZ materials has been explained by using the overall-effective-mass and the overall-scattering-time of electrons in the extended Drude model. However, their response to optical excitation is yet the last building block to complete the theory. In this paper, the concept of thermal energy is theoretically proposed to account for the total energy of conduction electrons exceeding their thermal equilibrium value. The time-varying thermal energy is adopted to describe the transient optical response of indium-tin-oxide(ITO), a typical ENZ material. A spectrally-resolved femtosecond pump-probe experiment was conducted to verify our theory. By correlating the thermal energy with the pumping density, both the giant change and the transient response of the permittivity of ITO can be predicted. The results in this work provide a new methodology to describe the transient permittivities of ENZ materials, which will benefit the design of ENZ-based nonlinear photonic devices. | Heng Wang Lixun Sun Kang Du Wending Zhang SooJin Chua Guixin Li Ting Mei | 2022 | Science China(Physics,Mechanics & Astronomy)2022，65，8： | 1 |
