Reconfigurable Intelligent Surfaces-Assisted Visible Light Communications Systems
Unlike in conventional radio frequency (RF) wireless systems, the visible light communications (VLC) channel is not isotropic. Thus, one fundamental challenge for VLC is the requirement of line-of-sight, i.e., a direct pathway between the transmitter and the receiver. They are therefore limited to a short transmission range and loss of signal may occur when the receiver rotates or moves. As a result, the performance of VLC systems, such as users' throughput and reliability, can significantly be affected by both device orientation and link blockage.
Meanwhile, reconfigurable intelligent surfaces (RIS) have recently emerged as a revolutionary concept that transforms the physical propagation environment into a fully controllable and customizable space in a low-cost low-power fashion. RIS research has become a focal point of interest in wireless communications communities as it offers a spectrum, energy, and cost-efficient approach for sustainable evolution in wireless systems. Although the integration of RIS in RF communications has been well investigated, its application in optical communications in general and VLC in particular is still in its infancy.
In this talk, the speaker will introduce optical RIS and discuss the different approaches to integrating RIS technology into VLC systems in order to harness their full potential. Additionally, the speaker will explore some research challenges and potential research directions.
