摘要

We propose a switchable multi-wavelength erbium-doped fiber laser based on a four-mode fiber Bragg grating. The four-mode fiber Bragg grating is fabricated in a hydrogen pre-loaded fiber by the phase mask method which can support four linearly polarized modes around 1550 nm. The five operation wavelengths are at 1547.5, 1546.8, 1546.0, 1545.1 and 1544.2 nm, respectively. Through adjusting the polarization state and the lateral offset coupling in cavity, the laser can be switched into the operation state of single, dual or triple wavelengths. The proposed laser has the advantages of simple configuration, stable operation and easy adjustment.
