Paper Abstract

We have demonstrated an optical scanner based on beam switching method fabricated on silicon photonics integrated circuit. Scanner is based on beam switching method. Scanner is composed of ring resonator multiplexer and grating array. Multiplexer determines the optical path and one of grating is selected for emitter. The scanning angle was 6 degree. Solid state scanner is suitable for Laser intensity direction and ranging (LIDAR) because of reliability and small factor. We fabricated and demonstrated an optical scanner based on beam switching method fabricated on silicon photonics integrated circuit. Scanner is all solid state and movement-free. Scanner is composed of ring resonator multiplexer and grating array. Multiplexer determines the optical path and one of grating is selected for emitter. LIDAR is promising sensor for automated cruising for automotive application and this report is considered to be a remarkable technology.
