Abstract
We demonstrate Type II difference-frequency generation (DFG) around in AlGaAs Bragg reflection waveguides using a pump around and a signal within the C-band range. Difference-frequency power of was obtained using a pump power of and a signal power of . Nonlinear conversion efficiency was estimated to be in a 1.5-mm-long sample. Using numerical simulations, the phase-matching bandwidth was predicted to be , while the measured DFG showed no sign of bandwidth limitation across a wavelength span of , which was limited by instrumentation.
