Summary form only given. There are presently two major issues in the research efforts on CW parametric fluorescence in waveguide optics. First, spontaneous parametric generation is the basic element toward integrated OPO's; second, quantum cryptography seems an interesting application even at very low power levels. Parametric fluorescence and oscillation were obtained in PPLN waveguides several years ago. Nevertheless, their counterpart in semiconductor waveguides is of great interest for integrated optoelectronics. While application of QPM technique to semiconductor waveguides is still in its infancy, the recent breakthrough in oxidized-AlGaAs (ALOX) nonlinear guided optics allows us to investigate integrated parametric fluorescence through form-birefringent phase matching.
