Optical Filter Bank Modeling and Design for Multi-Color Visible Light Communications

IEEE Photonics Journal, 2021
Multi-color visible light communication (MC-VLC) can achieve a multi-fold rate by taking advantage of multiple color channels. The optical filters for separating different colors are often designed for the normal incidence case only.
