Abstract

Couplers Gratings Laser radar Phase modulation Phased arrays Photodetectors Waveguide lasers
Most Photonic-Integrated FMCW LiDAR systems rely on beam steering with optical phased arrays, which require complex control of the individual phase modulators in the array. We propose a fully-integrated LiDAR chip that relies on tilted grating couplers, and does not require any phase modulators.
