Zusammenfassung:Beam steering with solid-state devices represents the cutting-edge technology for next-generation LiDARs and free-space communication transceivers. Here we demonstrate a platform based on a metalens on a 2D array of switchable silicon microring emitters. This platform enables scalable, efficient, and compact devices that steer in two dimensions using a single wavelength. We show a field of view of 12.4 degrees x 26.8 degrees using an electrical power of less than 83 mW, offering a solution for practical miniature beam steerers.
