Abstract

On-chip metasurfaces have been exploited to manipulate guided waves into free space with desired wavefronts and bridge the gap between guided modes and free-space optical fields. However, existing on-chip metasurfaces for guided wave radiation typically lack dynamic tunability and high-capacity multiplexing for their practical applications. Here, we present a dynamic waveguide-based holographic display enabled by on-chip metasurface network on lithium niobate on insulator platform. Based on geometric phase and detour phase, an on-chip multiplexed metasurface network implemented on a 2 × 2 waveguide crossing array is incorporated with a two-stage lithium niobate (LN) switch to construct an addressable framework. Benefiting from the multiplexing capability of on-chip metasurface and the fast electro-optical response of LN modulators, guided wave radiation in the form of eight holographic images is tunable and addressable at high speeds. This work exemplifies a scalable approach for dynamic manipulation of guided signals and paves the way towards holographic displays, high-capacity optical communications and integrated photonic information processing.
基于铌酸锂光子学的可寻址片上超表面网络动态全息显示。
片上超表面已被用于将导波操纵到具有所需波前的自由空间,并弥合导模和自由空间光场之间的差距。然而,现有的导波辐射片上超表面在实际应用中通常缺乏动态可调性和高容量复用。在这里,我们提出了一种基于片上超表面网络的动态波导全息显示技术,该技术应用于铌酸锂绝缘体平台上。基于几何相位和绕行相位,将基于2 × 2波导交叉阵列的片上复用超表面网络与两级铌酸锂(LN)开关相结合,构建可寻址框架。得益于片上超表面的多路复用能力和LN调制器的快速电光响应,以8个全息图像形式的导波辐射可以在高速下可调谐和可寻址。这项工作举例说明了一种可扩展的方法来动态操纵制导信号,并为全息显示、大容量光通信和集成光子信息处理铺平了道路。
