Low-cost and High-resolution Lidar with Wavelength Division Multiplexed Laser Array and Polarization-Interleaved Grating Couplers

2020 
By using wavelength division multiplexed laser array developed for optical communication, solid-state Lidar can achieve dramatic cost reduction. Angular resolution can be significantly increased using polarization-interleaved grating couplers that combine two orthogonal polarizations.
