Summary form only given. In summary, we have investigated wavelength conversion by quasi-phase-matched optical frequency conversion (OFG) in an AlGaAs waveguide. Linear conversion process and spectral inversion properties are demonstrated. The conversion efficiencies are polarization insensitive while the device also shows polarization diversity. Simultaneous conversions of multiple input wavelengths with no cross talk are demonstrated.
