Abstract
High-quality monoclinic optical waveguides were grown by liquid-phase epitaxy, and laser operation of an Yb-doped waveguide was demonstrated for the first time to our knowledge. Continuous-wave laser emission near was achieved with both surface and buried planar waveguides. An output power of was obtained in the fundamental mode and the slope efficiency was above 80%.
