Utilizing the frequency selection characteristic of ring resonators, self-injection-locking linewidth narrowing and frequency stabilization of distributed feedback laser diodes (DFB-LDs) can be achieved under the aid of ring resonators. In this paper, the self-injection-locking effects of a DFB-LD realized by two fiber ring resonators and an optical waveguide ring resonator are compared. The influences of the resonant peak bandwidth and transmission on linewidth narrowing are demonstrated. It is shown that the mode hopping can be significantly suppressed by employing the optical waveguide ring resonator. This is of great significance for practical applications and integration of the self-injection-locked DFB-LDs.

光纤和光波导环形谐振器对DFB-LD自注入锁定的比较

利用环形谐振器的频率选择特性,借助环形谐振器可以实现自注入锁定线宽的变窄和分布式反馈激光二极管(DFB-LD)的频率稳定。在本文中,比较了由两个光纤环形谐振器和一个光波导环形谐振器实现的DFB-LD的自注入锁定效果。证明了谐振峰值带宽和传输对线宽变窄的影响。示出了通过采用光波导环形谐振器可以显着地抑制模式跳变。这对于自注入锁定DFB-LD的实际应用和集成具有重要意义。
