Efficient sum-frequency generation in epitaxial GaAs/AlGaAs 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.
