Abstract

We report what is believed to be the first observation of second-harmonic generation by type I phase matching the bulk χ x y z ( 2 ) ( d 14 ) nonlinear coefficient using Bragg reflection waveguides. Second-harmonic power of 0.7 μ W was observed for a pump wavelength of 1587.8 nm with an average power of 25.2 mW and a pulse width of 2 ps at a repetition rate of 75.6 MHz . An order of magnitude enhancement between the phase-matched and un-phase-matched second-harmonic conversion efficiency has been observed. Conversion efficiency at the phase-matched wavelengths was 0.001%. The bandwidth of the second harmonic was found to be equal to 0.43 nm , agreeing with the theoretical predictions.
