Wavelength conversion via quadratic optical nonlinearity in AlGaAs waveguiding devices will be presented. We have fabricated periodically inverted AlGaAs waveguides using the sublattice reversal epitaxy technique and succeeded in quasi-phase-matched second-harmonic generation and difference-frequency generation with reasonably high efficiencies. We have proposed a novel AlGaAsbased wavelength conversion device utilizing birefringence in a thin high-index-contrast waveguide. © 2009 Optical Society of America.
