Abstract

A thermally fixed photorefractive Bragg grating is written in a single-mode Ti:Fe:Er:LiNbO3 channel waveguide and used to develop a distributed feedback–distributed Bragg reflector coupled cavity laser with a second broadband dielectric cavity mirror. The optically pumped λp=1480 nm,P=130 mW laser emits in single-frequency operation as much as 8 mW at λ=1557.2 nm with a slope efficiency of 22%. The laser wavelength can be thermo-optically and electro-optically tuned over 100 pm.
