Spectral transfer-learning-based metasurface design assisted by complex-valued deep neural network
Yi Xu, Fu Li, Jianqiang Gu, Zhiwei Bi, Bing Cao, Quanlong Yang, Jiaguang Han, Qinghua Hu, and Weili Zhang
Recently, deep learning has been used to establish the nonlinear and nonintuitive mapping between physical structures and electromagnetic responses of meta-atoms for higher computational efficiency. However, to obtain sufficiently accurate predictions, the conventional deep-learning-based method consumes excessive time

Generation of subwavelength inverted pin beam via fiber end integrated plasma structure
Zhengchuan Cai, Zhiqiang Quan, Libo Yuan, Jian Wang, and Houquan Liu
A pin-like beam is a kind of structured light with a special intensity distribution that can be against diffraction, which can be seen as a kind of quasi-nondiffracting beam (Q-NDB). Due to its wide applications, recently, numerous researchers have used optical lenses or on-chip integrated optical diffractive elements

635 nm femtosecond fiber laser oscillator and amplifier
Jinhai Zou, Qiujun Ruan, Tingting Chen, Hang Wang, Luming Song, Yikun Bu, and Zhengqian Luo
Although visible femtosecond lasers based on nonlinear frequency conversion of Ti:sapphire femtosecond oscillators or near-infrared ultrafast lasers have been well developed, limitations in terms of footprint, cost, and efficiency have called for alternative laser solutions. The fiber femtosecond mode-locked oscillator

Unveiling optical rogue wave behavior with temporally localized structures in Brillouin random fiber laser comb
Yuxi Pang, Qiang Ji, Shaonian Ma, Xian Zhao, Zengguang Qin, Zhaojun Liu, Ping Lu, Xiaoyi Bao, and Yanping Xu
The optical rogue wave (RW), known as a short-lived extraordinarily high amplitude dynamics phenomenon with small appearing probabilities, plays an important role in revealing and understanding the fundamental physics of nonlinear wave propagations in optical systems. The random fiber laser (RFL), featured with cavity-

Physics-constrained deep-inverse point spread function model: toward non-line-of-sight imaging reconstruction
Su Wu, Chan Huang, Jing Lin, Tao Wang, Shanshan Zheng, Haisheng Feng, and Lei Yu
Non-line-of-sight (NLOS) imaging has emerged as a prominent technique for reconstructing obscured objects from images that undergo multiple diffuse reflections. This imaging method has garnered significant attention in diverse domains, including remote sensing, rescue operations, and intelligent driving, due to its wid
