The Research of Optical Phased Array based Silicon Photonics Technology

In recent years, with the rapid rise of unmanned driving and robotics, there is an urgent need for high-performance and low-cost spatial 3D sensing lidar. As a pure solid-state beam scanning scheme of lidar, optical phased array based on silicon photonics technology has been widely studied in the world. This report first introduces the latest important research progress at home and abroad; Then,the report introduces some progress in the field of CUMEC based on its own 8-inch characteristic process line since early 2019, including the functional verification of 1×128/256 one-dimensional optical phased array (OPA), the verification of optoelectronic microsystems in which OPA was integrated with tunable light sources, and the exploration of coherent ranging technology based on OPA chips. Finally, some thoughts on the challenges faced by OPA technology in the future are introduced.
