DESCRIPTION:Unlike in conventional radio frequency (RF) wireless systems\, 
 the visible light communications (VLC) channel is not isotropic. Thus\, on
 e fundamental challenge for VLC is the requirement of line-of-sight\, i.e.
 \, a direct pathway between the transmitter and the receiver. They are the
 refore 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 s
 ystems\, such as users' throughput and reliability\, can significantly be 
 affected by both device orientation and link blockage.\n\nMeanwhile\, reco
 nfigurable intelligent surfaces (RIS) have recently emerged as a revolutio
 nary concept that transforms the physical propagation environment into a f
 ully controllable and customizable space in a low-cost low-power fashion. 
 RIS research has become a focal point of interest in wireless communicatio
 ns communities as it offers a spectrum\, energy\, and cost-efficient appro
 ach for sustainable evolution in wireless systems. Although the integratio
 n of RIS in RF communications has been well investigated\, its application
  in optical communications in general and VLC in particular is still in it
 s infancy.\n\nIn this talk\, the speaker will introduce optical RIS and di
 scuss the different approaches to integrating RIS technology into VLC syst
 ems in order to harness their full potential. Additionally\, the speaker w
 ill explore some research challenges and potential research directions.\n\
