Synthetic-Aperture Super-Resolution Imaging via Spatial-Frequency Shift in Near-Field Diffraction
Qihao Sun, Chunzheng Bai, Wenjing Fang +5
Grating-based computational imaging shifts high-spatial-frequency information into the detectable range, enabling super-resolution reconstruction. However, a fixed grating produces…

Uni-traveling-carrier photodetector with high-contrast grating focusing-reflection mirrors
Qingtao Chen, Wenjing Fang, Yongqing Huang +4
A novel uni-traveling-carrier photodetector (UTC-PD) structure with an integrated focusing-reflection (FR) mirror realized by a non-periodic concentric circular high-contrast grati…
