  • 摘要:

    窄线宽 器是光谱学和精密计量学等实验的基本组成部分。由于半导体 器对外部光学反馈十分敏感,所以可以利用光反馈的高带宽抑制半导体 器的相位噪声,进而压窄线宽。本文采用光纤布拉格光栅作为反馈元件,搭建了长外腔反馈回路。为了降低外界环境温度起伏和气流扰动的影响,对反馈光路的光纤控温,使得1小时内最大温度起伏从0.039 °C降低到0.003 °C。此外,测试了反馈带宽对 线宽的影响,尽管实验所用光纤布拉格光栅的带宽远大于自由运转的 线宽,但仍然可以观察到 线宽被压窄,且光纤光栅的带宽越小, 线宽越窄。对于此现象,分析认为在反馈回路中应该存在一种负反馈机制,可以将 线宽稳定到反馈光谱的某个斜率处,所以光纤光栅的反馈带宽越窄,反馈光谱的斜率越大,反馈越灵敏。通过调整光纤光栅的反馈功率在0~1 mW范围内改变,观察到当反射功率为0.8 mW时,光反馈将 线宽从自由运转的100.5 kHz压窄到最窄的11.5 kHz,0.2 kHz~2 MHz范围内的相位噪声降低约20 dB。
