Year All Realising high aspect ratio 10 nm feature size in laser materials processing in air at 800 nm wavelength in the far-field by creating a high purity longitudinal light field at focus Holes of 10–30 nm in diameter are produced on sapphire with a depth to width aspect ratio of over 16 and a zero taper with a single pulse longitudinal field. Zhaoqing LiOlivier AllegreLin Li Article Open Access 02 Dec 2022 Thickness bound for nonlocal wide-field-of-view metalenses A transmission-matrix-based framework is proposed to establish the intrinsic link between angular diversity and spatial footprint in multi-channel systems and to derive a bound on the thickness of nonlocal metasurfaces. Shiyu LiChia Wei Hsu Article Open Access 01 Dec 2022 Optical synaptic devices with ultra-low power consumption for neuromorphic computing Energy-efficient artificial photonic synapse is designed based on photo-sensitive BP/CdS heterostructure device, which can be used for high-performance brain-inspired neuromorphic computing. Chenguang ZhuHuawei LiuAnlian Pan Article Open Access 29 Nov 2022 Complex skin modes in non-Hermitian coupled laser arrays The Hatano–Nelson model with asymmetric couplings is demonstrated for the first time in phase locked laser arrays. The arrays exhibit steerable non-Hermitian skin effects. Yuzhou G. N.
