Paper Abstract

Orientation patterned GaAs waveguides for parametric conversion from near to mid-infrared have been fabricated by MOCVD growth on OPGaAs templates. A monolithic OPO cavity was formed by dielectric facet coating. Parametric oscillation characteristics were investigated using a pulsed source tunable in the range of 1.98-2.05μm. Type I and II parametric interactions have been observed, differing in QPM wavelength. OPO threshold power of 7W, using a pulsed pump, and 5.7W using a CW laser was obtained in a 13mm long waveguide of 39μm period. Overall Parametric peak power of 0.6W at pulsed pump peak power of 11.6W was generated at signal & idler wavelengths of 3.6μm & 4.5μm respectively and pump wavelength of 2.015μm. Tuning curves for Type I and type II parametric operation in OPGaAs WGs have been calculated and verified by the measured signal and idler wavelengths.
