Abstract :
We demonstrate continuous wave wavelength conversion between the near-IR) and mid-IR wavelength regimes based on sum-frequency generation (SFG) and difference-frequency generation (DFG) processes. Phase-matching (PM) is achieved for type-II nonlinear interaction using Bragg reflection waveguides. The normalized external conversion efficiency is estimated to be 26 %W-1 cm-2 for SFG in a 2.2 mm device and 5.8×10-2 %W-1 cm-2 for DFG in a 1.5 mm device. The PM bandwidths of the SFG and DFG processes were found to exceed 60 nm and 40 nm, respectively, which were limited by instrumentation.
