Abstract
Second-harmonic generation using the type-II polarization configuration is demonstrated in quasi-phase-matched GaAs/AlGaAs superlattice waveguides. Phase-matching wavelengths and conversion efficiencies were determined for several quasi-phase-matching periods using 1.9 ps pulses. Saturation effects at high input power were concluded to be the result of third-order nonlinear effects.
