Abstract

We demonstrate a tunable single-longitudinal-mode (SLM) narrow linewidth erbium-doped fiber (EDF) ring laser (EDFRL) in a cost-effective way. The laser incorporates an unpumped-EDF-based saturable absorber (SA) and a self-injection feedback loop for mode selection. The EDFDRL exhibits linear tunability of 12.57 pm/

基于可饱和吸收器和自注入反馈的可调谐窄线宽掺铒光纤环形激光器

我们以经济高效的方式展示了一种可调谐单纵模（SLM）窄线宽掺铒光纤（EDF）环形激光器（EDFRL）。该激光器集成了一个基于非泵浦掺铒光纤的可饱和吸收器（SA）和一个用于模式选择的自注入反馈回路。EDFDRL 具有 12.57 pm/$^{\circ }$C 的线性可调谐性，从 15 $^{\circ }$C 到 45 $^{\circ }$C，最大调谐范围为 0.3664 nm。在 200 mA 的泵浦电流下，我们实现了 SLM EDFRL，其特点是 75 dB 的高 OSNR 和 330 Hz 的超窄线宽。此外，它还具有出色的波长稳定性，最大波动仅为 11.23 pm。
