Unidirectional Focusing of Light Using Structured Diffractive Surfaces

open access: yesAdvanced Optical Materials, EarlyView.
This study presents a reciprocal diffractive unidirectional focusing design based on linear and isotropic layers. A set of cascaded diffractive layers is designed using deep learning to achieve efficient forward light focusing while suppressing backward propagation across various illumination angles.

Optical Wireless Communications with Metasurfaces: Current Status and Potential for Intelligent Communications

open access: yesAdvanced Photonics Research, EarlyView.
Optical wireless communications (OWCs) provide a promising alternative to spectrum‐congested microwave wireless communications. Recently, the use of metasurfaces with sub‐wavelength features for dynamic beam steering, beam manipulation, and spatial or optical‐angular‐momentum mode generation, conversion, and multiplexing in OWCs is proposed and ...
