| 1 | 光轨道角动量分离、成像、传感及微操控应用研究进展显示文摘光不仅可以携带自旋角动量,还可以携带轨道角动量。其中,自旋角动量与光波的圆偏振态有关,而轨道角动量来源于光波的螺旋相位结构。自Allen等1992年首次理论确认了光子轨道角动量的物理概念和内涵以来,这类具有特殊螺旋相位波前的新型光场吸引了越来越多的研究兴趣,在经典光学及量子光学领域均展示出了诸多重要的应用前景。本文从基础物理及应用物理两个层面出发,着重介绍了轨道角动量光束的制备与探测技术,特别是近年来轨道角动量调控在螺旋相衬成像技术、远程旋转多普勒效应探测技术及光学微操控技术等领域的研究进展。 | 杨伟东 邱晓东 陈理想 | 2020 | 中国激光2020，47，5： | 17 |
| 2 | Spin-decoupled metasurface for simultaneous detection of spin and orbital angular momenta via momentum transformation显示文摘With inherent orthogonality,both the spin angular momentum(SAM)and orbital angular momentum(OAM)of photons have been utilized to expand the dimensions of quantum information,optical communications,and information processing,wherein simultaneous detection of SAMs and OAMs with a single element and a single-shot measurement is highly anticipated.Here,a single azimuthal-quadratic phase metasurface-based photonic momentum transformation(PMT)is illustrated and utilized for vortex recognition.Since different vortices are converted into focusing patterns with distinct azimuthal coordinates on a transverse plane through PMT,OAMs within a large mode space can be determined through a single-shot measurement.Moreover,spin-controlled dual-functional PMTs are proposed for simultaneous SAM and OAM sorting,which is implemented by a single spin-decoupled metasurface that merges both the geometric phase and dynamic phase.Interestingly,our proposed method can detect vectorial vortices with both phase and polarization singularities,as well as superimposed vortices with a certain interval step.Experimental results obtained at several wavelengths in the visible band exhibit good agreement with the numerical modeling.With the merits of ultracompact device size,simple optical configuration,and prominent vortex recognition ability,our approach may underpin the development of integrated and high-dimensional optical and quantum systems. | Yinghui Guo Shicong Zhang Mingbo Pu Qiong He Jinjin Jin Mingfeng Xu Yaxin Zhang Ping Gao Xiangang Luo | 2021 | Light(Science & Applications)2021，10，4： | 14 |

| 5 | 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 |
| 6 | 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 |

| 13 | Creation and control of high-dimensional multi-partite classically entangled light显示文摘Vector beams,non-separable in spatial mode and polarisation,have emerged as enabling tools in many diverse applications,from communication to imaging.This applicability has been achieved by sophisticated laser designs controlling the spin and orbital angular momentum,but so far is restricted to only two-dimensional states.Here we demonstrate the first vectorially structured light created and fully controlled in eight dimensions,a new state-of-the-art.We externally modulate our beam to control,for the frst time,the complete set of classical Greenberger-Horne-Zeilinger(GHZ)states in paraxial structured light beams,in analogy with high-dimensional multi-partite quantum entangled states,and introduce a new tomography method to verify their fidelity.Our complete theoretical framework reveals a rich parameter space for further extending the dimensionality and degrees of freedom,opening new pathways for vetorilly structured light in the classical and quantum regimes. | Yjie Shen Iaac Nape Xilin Yang Xing Fu Mali Gong Darryl Naidoo Andrew Forbes | 2021 | Light(Science & Applications)2021，10，5： | 4 |

| 16 | Optical orbital angular momentum multiplexing communication via inversely-designed multiphase plane light conversion显示文摘Multiplexing and demultiplexing of optical orbital angular momentum(OAM)are critical operations in modedivision multiplexing communications.Traditional Dammann gratings,spiral phase planes,and optical geometric transformations are regarded as convenient methods for OAM mode(de)multiplexing.However,crosstalk between the different modes and the difficulty of mode multiplexing greatly limit their application to modedivision multiplexing communications.Here,using a set of inversely-designed phase planes,we demonstrate an OAM(de)multiplexer based on multiphase plane light conversion that can enable perfect OAM multiplexing communication.The sorted patterns are Gaussian-like and can be coupled easily into single-mode fiber arrays.Inputs from the fiber array are turned into coaxial OAM modes after the phase planes.OAM mode crosstalk generated by the multiplexer is less than-20 d B,with insertion loss of less than 2.6 d B.OAM modes are sorted by the demultiplexer with mode crosstalk below-10 d B,and the sorting results are coupled to the fiber array.OAM modes carrying 10 Gbit/s on–off keying signals were transmitted in a 5 km few-mode fiber.The measured bit-error-rate curves have power penalties of less than 10 d B.The proposed configuration is highly efficient and convenient and will be beneficial for potential applications in quantum information,information processing,and optical communications. | JUNCHENG FANG JINPEI LI ARU KONG YOUPENG XIE CHUXUAN LIN ZHENWEI XIE TING LEI XIAOCONG YUAN | 2022 | Photonics Research2022，10，9： | 3 |
| 17 | Ultrafast control of fractional orbital angular momentum of microlaser emissions显示文摘On-chip integrated laser sources of structured light carrying fractional orbital angular momentum(FOAM)are highly desirable for the forefront development of optical communication and quantum information-processing technologies.While integrated vortex beam generators have been previously demonstrated in different optical settings,ultrafast control and sweep of FOAM light with low-power control,suitable for high-speed optical communication and computing,remains challenging.Here we demonstrate fast control of the FOAM from a vortex semiconductor microlaser based on fast transient mixing of integer laser vorticities induced by a control pulse.A continuous FOAM sweep between charge 0 and charge+2 is demonstrated in a 100 ps time window,with the ultimate speed limit being established by the carrier recombination time in the gain medium.Our results provide a new route to generating vortex microlasers carrying FOAM that are switchable at GHz frequencies by an ultrafast control pulse. | Zhifeng Zhang Haoqi Zhao Danilo Gomes Pires Xingdu Qiao Zihe Gao Josep M.Jornet Stefano Longhi Natalia M.Litchinitser Liang Feng | 2020 | Light(Science & Applications)2020，9，1： | 2 |
