LIDAR SYSTEM BASED ON SILICON-BASED INTEGRATED MAGNETO-OPTICAL CIRCULATOR

摘要

A lidar system, including: a laser, an optical detector, a laser antenna, and a silicon-based integrated magneto-optical circulator. The silicon-based integrated magneto-optical circulator includes a silicon-based integrated Mach-Zehnder interference structure or a silicon-based integrated micro-ring structure, and silicon-based integrated magneto-optical waveguides. The silicon-based integrated magneto-optical circulator further includes an input port, a receiving port, and an emission port. The laser is aligned and coupled to the input port of the silicon-based integrated magneto-optical circulator via an optical fiber, a grating coupler, or an edge coupler. The optical detector is aligned and coupled to the receiving port of the silicon-based integrated magneto-optical circulator via the optical fiber, the grating coupler, or the edge coupler. The laser antenna is aligned and coupled to the emission port of the silicon-based integrated magneto-optical circulator via the optical fiber, the grating coupler, or the edge coupler.
