Abstract
Efficient sum-frequency generation in epitaxial waveguides is reported. Phase matching is achieved for type II nonlinear interaction using Bragg reflection waveguides. Continuous-wave signal and pump in wavelength window were used for upconversion of photons to the region. For a pump and signal with powers of and , sum-frequency power of was measured. The normalized conversion efficiency was estimated to be in a device with a length of . The bandwidth of the process was found to exceed .
