Abstract

Wavelength conversion via quadratic optical nonlinearity in AlGaAs waveguiding devices will be presented. Devices reported in this article include periodically inverted quasi-phase matching (QPM) devices and thin- rectangular high-index-contrast birefringence phase matching devices. Special emphasis will be placed on GaAs/AlGaAs QPM waveguides fabricated based on epitaxial growth technique (sublattice reversal epitaxy) we have developed for growing spatially inverted semiconductors. We have succeeded in demonstrating QPM second-harmonic generation and difference-frequency generation with reasonably high efficiencies.
