    A stable and wavelength-tunable C- plus L-band fiber double-ring laser, which uses a two-stage hybrid amplifier with a semiconductor optical amplifier and an erbium-cloped fiber amplifier, has been proposed and experimentally demonstrated. Based on the double-ring configuration, the proposed fiber ring laser exhibits more stable output wavelengths and powers than the single-ring laser. A wide tunable range of 1540 to 1620 nm, a side-mode suppression ratio (SMSR) of > 31.2 dB/0.05 nm over a wide tuning range from 1550 to 1612 nm, and an output power of > 2 dBm over the operation range of 1546 to 1608 nm have been achieved.

    A tunable C-plus-L-band fiber ring laser, based on a semiconductor optical amplifier, which directly connects an erbium-doped fiber amplifier with a 16 m long erbium-doped fiber, has been proposed and experimentally investigated. A side-mode suppression ratio of > 40 dB/0.1 nm and an output power of >3 dBm in the operating range from 1552 to 1610 nm have been achieved for this ring laser.

    We have proposed and experimentally demonstrated a stabilized and tunable erbium-doped fiber ring laser by using a Fabry-Perot laser and a fiber Fabry-Wrot filter. The sidemode suppression ratio of >30 dB/0.1 nm and the output power of >2.2 dBm can be achieved while this ring laser is tuned from 1528.28 to 1559.64 nm with the step of 1.12 nm. The wavelength variation of less than 0.01 nm and the power fluctuation of less than or equal to0.04 dB have also been obtained. When the constant output power is controlled by adjusting the bias current of 980-nm pump laser, the power variation of less than +/-0.05 dB can be obtained over the entire tunable range.
