We review our recent progress on frequency conversion in integrated devices, focusing primarily on experiments based on strip-loaded and quantum-well intermixed AlGaAs waveguides, and on CMOS-compatible high-index doped silica-glass waveguides. The former includes both second- and third-order interactions, demonstrating wavelength conversion by tunable difference-frequency generation over 100 nm bandwidth, as well as broadband self-phase modulation and tunable four-wave mixing. The latter includes four-wave mixing using low-power continuous- wave light in microring resonators as well as hyperparametric oscillation in a high quality factor resonator, toward the realization of an integrated multiple wavelength source with important applications for telecommunications, spectroscopy, and metrology.
