Abstract

A C-band tunable dual-wavelength laser for a RoF light source is demonstrated. The difference frequency was tunable in the range of 22.6 GHz to 192.0 GHz. The generated dual-wavelength laser amplified by EDFA could be converted to a corresponding radio frequency through a high-speed photodetector.
