A tunable multiwavelength fiber laser based on double Sagnac loops is proposed and demonstrated. Comb filter characteristics of single and double Sagnac loops are analyzed by Jones matrix. Simulated results show that there are better tunability and controllability with double loops than with a single loop, and this also has been confirmed by experimental results. By adjusting the polarization controller and the length of the polarization maintaining fiber the wavelength range, wavelength spacing, and laser linewidth can be tuned. Experimental results indicate that the linewidth of the multiwavelength fiber laser was 0.0187 nm and the optical sidemode suppression ratio was 50 dB.
提出并演示了一种基于双萨格纳克环的可调谐多波长光纤激光器。通过琼斯矩阵分析了单萨格纳克环和双萨格纳克环的梳状滤波器特性。仿真结果表明，双环比单环具有更好的可调谐性和可控性，实验结果也证实了这一点。通过调整偏振控制器和保偏光纤的长度，可以调谐波长范围、波长间隔和激光线宽。实验结果表明，该多波长光纤激光器的线宽为0.0187nm，光边模抑制比为50dB。
