| 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. |
