4 Gbps direct modulation of 450 nm GaN laser for high-speed visible light communication
Optics Express
|July 21, 2015
Abstract:
We demonstrate high-speed data transmission with a commercial high power GaN laser diode at 450 nm. 2.6 GHz bandwidth was achieved at an injection current of 500 mA using a high-speed visible light communication setup. Record high 4 Gbps free-space data transmission rate was achieved at room temperature.
