Abstract

Visible light communications at high frequency (up to 2.5 Gbit/s) using a directly modulated 422 nm Gallium-nitride (GaN) laser diode is reported. An optical bandwidth of approximately 1.4 GHz is measured. Free space, visible light communications (VLC) at data rates of up to 2.5 Gbit/s are demonstrated. Error free data transmission and clearly open eye diagrams are observed.
