Wafer-bonding is an effective method of realizing a domain altered waveguide for nonlinear optical applications. Wavelength conversion by quasi-phase-matched difference frequency generation (DFG) in a wafer-bonded AlGaAs waveguide has been demonstrated. The wide conversion bandwidth (/spl sim/90 nm), polarization diversified operation, and polarization independent conversion efficiency indicate its potential for WDM network applications. Spectral inversion and linear conversion properties also imply its capability to accommodate all signal formats and protocols including analog and frequency modulation. A significant improvement in the conversion efficiency is expected from reduction of scattering losses by improved OMCVD growth and fabrication processes.
