Parametric fluorescence in low-loss oxidized aluminum gallium arsenide heterostructure waveguides is quantitatively analyzed. A parametric fluorescence efficiency as high as 6×10[sup -7] W/W has been measured in a 3.2-mm-long waveguide. This corresponds to a normalized conversion efficiency, scaled with the waveguide length, of about 1000% cm-2 W-1, eight times higher than with LiNbO[sub 3] waveguides. This opens the perspective of a microoptical parametric oscillation threshold below 100 mW. © 2001 American Institute of Physics.

    For wavelengths near the quantum well absorption edge it is found that fewer quantum wells favor ideal phase modulation in GaAs/AlGaAs waveguide modulators. This is due to the dominance of the linear electro-optic effect over quantum absorption effects in the separate confinement waveguide. For...
