摘要

We report on the fabrication of optical channel waveguides supporting both visible and IR TE and TM confinement in a hybrid system composed of a Nd:YVO_(4) laser gain medium glued to a potassium titanyl phosphate (KTP) nonlinear crystal. The microphotoluminescence and second harmonic confocal images of the fabricated waveguides have revealed that the laser and nonlinear properties of the constituent crystals have not been deteriorated because of the waveguide inscription. The resulting structures emerge as promising candidates for the development of multifrequency waveguide lasers.
