Abstract
Visible light communication (VLC) is an exciting research area. VLC offers a significantly greater spectrum than radio frequency and is ideal for data communication. In VLC, the visible light spectrum, from 400 to 700 nm, is used for both lighting and communication. Gallium nitride-based light-emitting diodes (LEDs) and laser diodes are the optical sources in visible light communications. Laser diodes have an advantage over LEDs in visible light communication. VLC has applications in underwater communication, vehicle-to-vehicle communications, among others.
