Abstract

HVPE growth of orientation patterned GaAsP (OP-GaAsP) layers with thickness exceeding 600 m and with excellent domain fidelity is accomplished for several arsenic-phosphorus compositions to obtain desired optical properties. This novel ternary material system could be an ideal candidate as compared to those of widely explored QPM materials – GaAs and GaP, for nonlinear frequency conversion in the mid- and long-wave infrared based on some specific pump sources, such as mode-locked Er-fiber lasers. Recent demonstration of second harmonic generation in an OP-GaAs0.15P0.85 structure brings us a step closer to implement such GaAsP QPM structures as frequency conversion devices.
