摘要

元表面为非线性光学领域的众多创新应用提供了便利。然而，在像素级动态调整非线性响应非常具有挑战性。最近的研究提出了一种新方法，通过将多量子阱（MQW）带间跃迁产生的巨大非线性响应与等离子纳米谐振器结合起来，对三次谐波产生（THG）的局部振幅和相位进行电子操控。所展示的方法可为通过电调谐实现具有多种功能的非线性光学元件铺平道路，并促进激光雷达、三维显示、光加密、光计算等创新应用的发展。

High efficiency and dynamic modulation of nonlinear metasurfaces

Metasurfaces have facilitated numerous innovative applications in the scope of nonlinear optics. However, dynamically tuning the nonlinear response at the pixel level is very challenging. Recent work proposed a novel method to electrically manipulate the local amplitude and phase of third-harmonics generation (THG) by integrating the giant nonlinear responses resulting from intersubband transitions of multiple quantum wells (MQW) with plasmonic nano-resonator. The demonstrated method may pave the way to realize nonlinear optical elements with versatile functionalities by electrically tuning and promoting the advancements of innovative applications such as lidar, 3D displays, optical encryption, optical computing, and so on.
