报告内容简介：

The realization of all-optical integration and optical computing has always been our goal. Furthermore, quantum optical computing is believed to solve certain problems substantially faster than traditional computing methods. Integrated quantum photonic circuits are a promising approach to realizing future quantum information processing. To achieve large-scale photonic chips, as many all-optical logic devices as possible are expected to be integrated on chips. This requires devices to be as small as possible, whether for classical systems or quantum systems. In this talk, we will introduce our recent works on ultra-compact all-optical logic devices and integrated chips on silicon photonic platforms by topology optimization. Inverse-designed universal quantum logic gates for super-compact quantum circuits will also be discussed. Besides ultra-compact properties, robust properties are also very important. In this talk, we will also introduce our recent works on design and experimental realization oftopologically-protected all-optical logic gates based on silicon photonic crystal slabs.
