Abstract
LiDAR, or light detection and ranging, is an active remote sensing system that accurately survey the surrounding environment. As the essential component of a LiDAR system, an optical phased array (OPA) plays a fundamental role in beamforming. Generally speaking, OPAs usually require a narrow beam width and a large steering range. Grating lobes are found to be limiting the steering range due to the inherently large uniform element spacing in the traditional phased array design. In this work, we provide design solutions to suppress and eliminate the grating lobes of three types of OPAs: rectangular, circular, and randomly distributed OPAs.
