Parametric fluorescence at 2.1 µm is observed in oxidized, form-birefringent AlGaAs waveguides. The signal level measured is approximately 15 pW, over the range of 1.9–2.5 µm. The possibility of realizing an optical parametric oscillator is discussed, and reduction of the internal losses is shown to require optimization of the oxidation process.
