Background Introduction Photon integrated circuits (PICs) are significant for achieving high-speed data transmission. However, traditional photon integrated circuits, which only use a single plane or a limited number of stacked planes, are restricted in optical signal routing. Additionally, coupling losses need to be as low as possible for practica...

Broadband Achromatic Spatial Differential Imaging with Optical Spin-Orbit Coupling Background Introduction In image processing, traditional spatial differentiation is typically accomplished through digital electronic computation. However, many big data applications require real-time and high-throughput image processing, which poses a tremendous cha...
