A new method for suppression of coupling from guided optical modes into cladding modes in an optical fiber Bragg grating using a fiber with a strongly depressed cladding is proposed. Strong suppression of the coupling has been demonstrated both theor

We report the first room temperature laser operation of Tm3+:LiNbO3. The gain medium was a Ti-indiffused waveguide with active laser doping by thermal indiffusion. Lasing occurred at 1.85µm and results are presented for devices in single-domain, mul

Rare earth doped LiNbO3 is an interesting laser host as it has nonlinear, electro-optic and acousto-optic properties. Low-loss waveguides can also be made in this material and then combined with thermal indiffusion of the laser dopant. LiNbO3 can als

We report laser action in a Ti-diffused LiNbO3 waveguide doped with trivalent Yb ions by thermal indiffusion. Lasing was observed at 1008, 1030, and 1060 nm with thresholds as low as 15-mW launched pump power. We reduced photorefractivity, which init
