Abstract :
The authors report on a study of optical gain in chromium-doped LiNbO3 waveguides formed by the proton-exchange process. Optical gain in proton-exchanged Cr:LiNbO3 channel waveguides has been measured for the first time. These waveguides show potential for diode-laser pumping of an integrated, broadband tunable laser in the 750-1150 nm spectral range.
