摘要：

We demonstrate a single polarization, narrow linewidth hybrid laser by using a semiconductor gain chip and a birefringence silica-on-silicon waveguide Bragg grating. The hybrid laser shows good linewidth and single polarization characteristics with the selective polarization mode feedback of high birefringence grating. The temperature phase modulation on the characteristics of the potentially lasing modes is displayed. In addition, the performances of different mode power, side mode suppress ratio, spectrum and linewidth during temperature tuning are characterized. We based on the rate equation method and the chirp factor reduction theory analysis the variation of laser linewidth with power and lasing wavelength. The best linewidth achieves 4.36 kHz and the best polarization extinction ratio is 38.6 dB. The output power in fiber is 6.58 mW.
