Visible light communication (VLC) using white LEDs for lighting has attracted attention due to the increasing scarcity of radio-frequency spectrum. However, conventional white LEDs that combine blue LEDs with phosphors are limited in communication speed by the slow optical response of the phosphors. Therefore, wavelength-division multiplexing (WDM) using phosphor-free, multi-wavelength LEDs is a promising approach for achieving higher speed and greater capacity in VLC. In this presentation, we report estimated achievable communication speeds and the number of channels when the entire visible spectrum is covered using InGaN-based LEDs.
