Roadmap on structured light lasers

Qiang Liu, Xing Fu, Zilong Zhang, Andrew Forbes et autres

Abstract How to further increase the information capacity carried by structured light by extending and coupling many degrees of freedoms of light over time and frequency domains, such as polarizations and spatial structures, is one of the frontiers in optics and photonics. …

Integration of chalcogenide-based phase change materials and metasurfaces

Xinbo Sha, Q F Liu, Yixuan Zeng, Yubin Fan et autres

Metasurfaces exhibit excellent performance in optical field modulation, but traditional designs are typically fixed once manufactured, which limits their adaptability to dynamic tuning requirements. Then, tunable materials, such as phase change materials (PCMs), have attracted significant attention in nanophotonics due to their …

Intensity-asymmetric wavefront shaping in nonlocal meta-lens

Jin Yao, Zhihui Wang, Yubin Fan, Ke Zhang et autres

Asymmetric wavefront shaping can unlock essential functionalities for next-generation photonic systems, such as unidirectional transmission, nonlinear signal routing, and nonreciprocal light control. However, achieving these functionalities in passive nonlinear metasurfaces remains challenging due to the required trade-offs among nonlinear efficiency, phase modulation, …

Meta-device for sensing subwavelength lateral displacement

Shufan Chen, Yubin Fan, Hao Li, Xiaodong Qiu et autres

Accurate transverse displacement measurement is essential for precise mask-to-wafer positioning in lithography. While lateral displacement metrology has achieved nanometer-level precision, the limitations imposed by coherent state and grating challenge in-situ measurement speed and precision. Here, we introduce a two-photon state transverse displacement …

Compound metalens-based miniature two-photon microscope for large-FOV imaging in freely behaving animals

Yao Zhang, Yufei Zhu, Hongchen Jiao, Yanhui Hu et autres

Abstract Miniaturized two-photon microscopes (m2PMs) enable high-resolution, deep-brain imaging in freely behaving animals. However, the trade-offs among weight, form factor, and optical performance in conventional refractive objectives present major obstacles to achieving large field-of-view (FOV), high-resolution imaging in weight-sensitive or multiregion applications. …

All-dielectric Schrödinger colours across the visible spectrum

Yingjie Li, Jun Yin, Chi Zhang, Yao Zhang et autres

Structural colours, which arise from nanostructures, are pervasive in nature and play a pivotal role in numerous modern applications. Traditional approaches usually deviate from the concept of Schrödinger’s pixels and thus have restricted performance in colour gamut and chiaroscuro presentation. Here, we …

Dispersive Meta-lens Thermometry for High-temperature Measurements

Yulun He, Mu Ku Chen, Mingrui Huang, Yifei Zhang et autres

Temperature is a fundamental parameter that governs the rate and extent of thermal energy transfer. Accurate measurement is crucial for safe and efficient energy exchange. Radiation thermometry, favoured for high-temperature measurement due to its non-invasive nature, often requires bulky optics like interference …

Multiuser all-optical quantum network based on metasurfaces

Shengshuai Liu, Lin Li, Mengting Ning, Yanbo Lou et autres

A crucial aspect of quantum information is the establishment of multiuser quantum networks, ensuring secure transmission of information among separated users. However, establishing a large-scale network remains a substantial challenge, requiring massive and compact Einstein-Podolsky-Rosen (EPR) entangled states. Here, we experimentally generate …

Dynamically tunable long-range coupling enabled by bound state in the continuum

Haijun Tang, Can Huang, Yuhan Wang, Xiong Jiang et autres

Formation and dynamic control of strong coupling among cavities are essential to realize advanced functional photonic and quantum circuits. Especially for cavities at distant distance or arbitrary locations. Conventional approaches suffer from short coupling distance, poor controllability, fixed locations and low wavelength …

On-chip integration of achromatic metalens arrays

Yao Zhang, Xiong Jiang, Geyang Qu, Jing Han et autres

Broadband achromatic metalenses and metalens arrays hold promise for enabling high-performance optical imaging in a compact form factor. Conventional visible-light achromatic metalenses are composed of transparent and high-refractive-index TiO2 or GaN nanopillars, but are strongly limited in mainstream silicon-based complementary metal-oxide-semiconductor (CMOS) …
