Integrated silicon photonics introduces Optical Phased Arrays (OPAs), a breakthrough in free-space satellite communications and LIDAR. Overcoming limitations of conventional technologies, silicon-based OPAs offer compact, high-resolution, and energy-efficient beam steering. Recent advancements in concentric ring-organized chip-scale silicon OPAs effectively suppress sidelobes, expanding the steering range and achieving narrower beamwidths.
