Abstract:
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.
