Radio frequency (RF) spectrum is highly occupied and adding further broadband channels
to fulfill the exiting user requirements has become difficult. Optical free-space …

Micro-light emitting diode (micro-LED) is an emerging display technology with excellent
performance of high contrast, low power consumption, long lifetime, and fast response time …

Two-terminal devices are building blocks for modern electronic systems. However, the
typical two-terminal architecture can limit functionality and performance. Here we report a …

The optical wireless communication (OWC) technology explores the broad unregulated
optical spectrum to provide high-speed wireless communications, and the visible, ultraviolet …

In this paper, we investigate the use of intelligent reflecting surfaces (IRSs) to relax the line-
of-sight requirement of free space optical (FSO) systems. Considering a Gaussian laser …

Free-space optical communication becomes challenging when an occlusion blocks the light
path. Here, we demonstrate a direct communication scheme, passing optical information …

Reconfigurable intelligent surfaces (RISs) are an emerging technology aimed to enhance
the energy and spectrum efficiency of wireless communication links by reconfiguring the …

We propose two types of intelligent reflecting systems based on programmable
metasurfaces and mirrors to focus the incident optical power towards a visible light …

Recently, remarkable efforts have been made in develo** wireless communication
systems at ultrahigh data rates, with radio frequency (RF) carriers in the millimeter wave (30 …

Reconfigurable intelligent surface (RIS) is an excellent use case for line-of-sight (LOS)
based technologies such as free-space optical (FSO) communications. In this paper, we …
