Dual-wavelength Fiber Laser Based on FBG in Sagnac Loop
摘要
提出了一种内嵌光纤Bragg光栅(FBG)对的Sagnac环结构双波长掺铒光纤(EDF)环形激光器。对内嵌FBG对的Sagnac环的滤波特性进行了理论分析，实验获得了输出波长分别为1554.92nm和1555.2nm的稳定双波长光纤激光，边模抑制比约为65dB，功率稳定性优于0.2dB，波长稳定性优于0.02nm。
Abstract
In this paper, it is proposed a dual-wavelength Er-doped fiber (EDF) ring laser based on a dual-wavelength fiber Bragg grating (FBG) in the Sagnac loop interferometer. The filtering properties of Sagnac loop were theoretically analyzed, and stable dual-wavelength lasers were obtained with output wavelengths of 1554.92nm and 1555.2nm, respectively. The side-mode suppression ratio is about 65dB, and the power stability and the wavelength stability are better than 0.2dB and 0.02nm, respectively.
