We developed a low-loss switch using SiN waveguides and thermo-optic micro-ring resonators (MRRs) for 2D scanning in non-mechanical FMCW LiDAR. By replacing conventional MZI switches, we reduced the round-trip loss to 4 dB and successfully demonstrated SLG selection with all eight MRRs. Beam scanning and LiDAR operation will be demonstrated in future work.
