Abstract

We demonstrate a hybrid solid-state beam scanner based on 32-channel silicon nitride optical switch with the assistance of transmission blazed grating. The optical switch exhibits rather low power consumption of 7.2 mW/π. Besides, end-fire antennas offer high optical efficiency with less reflection. Non-mechanical two-dimensional beam steering with range of 14.32° × 9.94° and beam divergence of <0.1° is achieved by wavelength tuning and onchip optical path switching. The proposed system eliminates complex control and time-consuming array phase calibration, providing a flexible, scalable and effective solution for all solid-state coaxial light detection and ranging (LiDAR) technology.
