Abstract:
Visible light communications using a Gallium-nitride (GaN) laser diode is reported. Devices, which are cased in TO packages, show modulation bandwidths of up to 1.4 GHz. We demonstrate error-free data transmission, defined as transmission of 1×10(-9) bits without any errors, at 2.5 Gbit/s with a sensitivity of 11.5 dBm.
