title: Continuous-wave second harmonic generation in Bragg reflection waveguides.
abstract: We report the observation of continuous-wave second harmonic generation for a pump at 1559.9 nm in type-I phase-matched Bragg reflection waveguide using the GaAs/Al(x)Ga(1)1-(x)As material system. For an internal pump power of 94 mW, phase-matched second harmonic power of 23 nW was measured in a waveguide with a length of 1.96 mm and ridge width of 4 mum. The internal conversion efficiency of the process was estimated as 6.8 x 10-(3) %W-(1)cm-(2). The full-width at half-maximum bandwidth of the nonlinear process was found to be 0.91 nm.
