Angle-insensitive spectral imaging based on topology-optimized plasmonic metasurfaces
Jiawei Yang, Kaiyu Cui, Yidong Huang +3
On-chip spectral imaging based on engineered spectral modulation and computational spectral reconstruction provides a promising scheme for portable spectral cameras. However, the a…
Metasurface-Based Free-Space Multi-port Beam Splitter with Arbitrary Power Ratio
Tian Tian, Yuxuan Liao, Xue Feng +4
A beam splitter (BS) is one of the most critical building blocks in optical systems. Despite various attempts of flat-type BSs to miniaturize the conventional cube BS reported, it…
On-chip mechanical exceptional points based on an optomechanical zipper cavity
Ning Wu, Kaiyu Cui, Qiancheng Xu +4
Exceptional points (EPs) represent a distinct type of spectral singularity in non-Hermitian systems, and intriguing physics concepts have been studied with optical EPs recently. As…
All-Optical Image Identification with Programmable Matrix Transformation
Shikang Li, Baohua Ni, Xue Feng +4
An optical neural network is proposed and demonstrated with programmable matrix transformation and nonlinear activation function of photodetection (square-law detection). Based on…
Dynamic brain spectrum acquired by a real-time ultra-spectral imaging chip with reconfigurable metasurfaces
Jian Xiong, Xusheng Cai, Kaiyu Cui +12
Spectral imaging paves way for various fields and particular in biomedical research. However, spectral imaging mainly depending on spatial or temporal scanning, cannot achieve high…
