Parametric fluorescence at 2.1 mu m is observed in oxidized, form-birefring
ent AlGaAs waveguides. The signal level measured is approximately 15 pW, ov
er the range of 1.9-2.5 mu m. The possibility of realizing an optical param
etric oscillator is discussed, and reduction of the internal losses is show
n to require optimization of the oxidation process. (C) 1999 Optical Societ
