摘要

本文研究了窃窃私语腔微谐振腔与激光腔之间相位差的反馈控制在稳定自注入锁定中的应用。通过分析相位差与微谐振腔透射光强的关系，以及所选移相器件和控制器的特性，成功地将相位差维持在设定点上。通过这种相位差控制机制，光纤耦合连接的高质量微谐振腔半导体激光器具有稳定的自注入锁定特性。关键性能指标包括200 Hz左右的窄线宽和最小归一化输出波长艾伦偏差1×10-10。该方法为自注入锁定激光稳定提供了一种可靠的解决方案。

Stabilization of a whispering gallery mode self-injection locked laser based on phase difference control.

We investigate the application of feedback control of phase difference between the whispering gallery mode microresonator and the laser cavity, for the stabilization of self-injection locking. By analyzing the relationship between phase difference and microresonator transmitted light intensity, as well as the characteristics of selected phase shift devices and controller, the phase difference is successfully maintained at the set point. Through this phase difference control mechanism, the semiconductor laser with a high-quality microresonator coupled and connected by optical fibers exhibits a stable self-injection locking. Key performance metrics include a narrow linewidth of around 200 Hz and a minimum normalized output wavelength Allan deviation of 1×10^-10. This approach presents a promising and reliable solution for the self-injection locked laser stabilization.
