Abstract:
We report on continuous-wave sum and difference frequency generation in selectively oxidized AlGaAs waveguides designed for degenerate spontaneous parametric down-conversion at 1.55 μm. Sum frequency generation with two pumps around this wavelength is observed with a conversion efficiency η = 1080%W-1cm-2. Difference frequency generation is also performed near degeneracy, with an external conversion efficiency η(ext) = 9.7%W-1cm-2 and a tunability of 570 nm. These results are promising for the feasibility of an integrated telecom source based on parametric fluorescence.
