A tunable and switchable erbium-doped fiber (EDF) laser based on modal interference has been proposed and experimentally demonstrated in this paper. Here a core-offset structure has been used to excite the cladding modes and a segment of polarization maintaining fiber inserted in a Sagnac loop interferometer has been used as wavelength selective component. By adjusting the statement of polarization controller (PC) and the bending of the core-offset structure, a tunable and switchable fiber laser with the signal-to-noise ratio (SNR) of more than 50 dB has been achieved in this paper.
