Efficient sum-frequency generation in epitaxial Ga As Al Ga As waveguides is reported. Phase matching is achieved for type II nonlinear interaction using Bragg reflection waveguides. Continuous-wave signal and pump in 1550 nm wavelength window were used for upconversion of photons to the 775 nm region. For a pump and signal with powers of 0.69 mW and 0.35 mW , sum-frequency power of 35 nW was measured. The normalized conversion efficiency was estimated to be 298 % W 1 cm 2 in a device with a length of 2.2 mm . The bandwidth of the process was found to exceed 60 nm .
