We report what is believed to be the first observation of second-harmonic generation by type I phase matching the bulk ${\chi }_{xyz}^{\left(2\right)}$ $\left(d_{14}\right)$ nonlinear coefficient using Bragg reflection waveguides. Second-harmonic power of $0.7\mathrm{\mu }\mathrm{W}$ was observed for a pump wavelength of $1587.8\mathrm{nm}$ with an average power of $25.2\mathrm{mW}$ and a pulse width of $\sim 2\mathrm{ps}$ at a repetition rate of $75.6\mathrm{MHz}$ . 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 $0.43\mathrm{nm}$ , agreeing with the theoretical predictions.
