Abstract
This paper proposes a novel design of a visible light communication (VLC) system enhanced by an optical intelligent reflecting surface (OIRS) to support large-scale indoor applications. The system leverages the programmable reflectivity of the optical IRS to optimize light propagation, thereby improving signal coverage and quality across expansive indoor environments. A detailed system model is formulated, incorporating the characteristics of VLC channels and the controllable properties of the optical IRS. Through mathematical analysis and extensive simulations, we demonstrate that the proposed system significantly enhances the signal-to-noise ratio (SNR) and extends coverage compared to conventional VLC systems. The findings validate the efficacy of the optical IRS-based VLC system as a robust solution for high-speed, reliable wireless communication in large indoor spaces such as warehouses, shopping malls, and conference centers.
