Abstract

A stable and wavelength-tunable S-band erbium-doped fiber (EDF) ring laser with single-longitudinal-mode oscillation over the operating range of 1480.6 to 1522.9 nm is proposed and experimentally demonstrated. The proposed ring laser provides a fine mode restriction and guarantees the single-frequency operation based on a shorter length EDF serving as auto-tracking filter. Therefore, the performances of output power of > 10 dBm, power stability of < 0.05 dB, central wavelength variation of <0.01 nm, and side-mode suppression ratio (SMSR) of > 49.1 dB have been experimentally demonstrated in the operating range of 1488.7 to 1505.7 nm.
