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° × 26.8° using an electrical power of less than 83 mW, offering a solution for practical miniature beam steerers.

基于硅光子上金属元素的2D光束转向器

固态设备的光束控制代表了下一代LiDAR和自由空间通信收发器的尖端技术。在这里，我们演示了基于可切换硅微环发射器2D阵列上的金属元素的平台。该平台可实现可扩展，高效且紧凑的设备，这些设备可使用单个波长进行二维控制。我们以小于83 mW的功率显示了12.4°×26.8°的视场，为实用的微型光束转向器提供了解决方案。
