Abstract :
A novel ring fiber laser based on Er-doped photonic crystal fiber (EDPCF) is demonstrated. EDPCF is used as gain medium to implement stable CW operation. The laser output wavelength can be continuously tuned over the range from 1529 to 1535 nm by adjusting the polarization state of the light inside the cavity. Stable dual-wavelength CW operation is also observed with proper settings of the intracavity polarization controllers. The laser stability in terms of the output power and the operation wavelength is characterized, and less than ±0.05 dB power fluctuation as well as 18 pm wavelength perturbation are obtained.
