An integrated workflow for the optimization of MicroLED transmitters in visible light communication systems

Abstract
This work presents a five-step simulation workflow for designing and optimizing microLED-based indoor Visible Light Communication (VLC) systems using Ansys Lumerical FDTD, Ansys Zemax OpticStudio and Ansys optiSLang. The workflow begins with device-level modeling of a microLED transmitter to obtain far-field emission patterns, followed by system-level ray tracing in an empty interior modeled in Zemax. OptiSLang is then used to automate the optimization of microLED design to achieve a high coverage using a grid of beams mounted on the ceiling. Finally, a realistic 3D environment is modeled in Zemax, where the optical power is measured at a receiver of a user's device and the communication channel characteristics are evaluated. This integrated approach can greatly speed up the design and evaluation process of high-performing indoor LiFi systems and allows for accurate predictions of key metrics and enhanced multi-objective optimizations.
