“…So, the degree of PC will be rotated uncertainly, when different lasing wavelength is generated. As shown in figure 1(a), the CP 1 , CP 2 , PC and 200 m SMF are exploited to construct an MZI in the ring cavity serving as the comb filter [10]. Here, the dual-arm length of L 1 and L 2 of the MZI structure are 202 and 6 m long, respectively.…”

“…Nevertheless, because of the longer fiber length and EDF's homogeneous broadening effect, the EDF laser could result in the multiple and unstable longitudinal-mode fluctuations [9]. To mitigate the dense longitudinal-mode variations, several associated methods have been proposed, such as utilizing the Mach-Zehnder interferometer (MZI) based comb filter [10], composite-fiber-ring configuration [11,12], saturable absorber (SA) based filter [13,14] and optical feedback injection effect [2,15]. Commonly, the most of EDF lasers operated in the C-band scope from 1528 to 1562 nm.…”

In the study, we demonstrate an erbium-doped fiber (EDF) laser system by integrating the Mach-Zehnder interferometer (MZI) and triple-fiber-ring structures to generate the single-longitudinal-mode (SLM) output in L-band bandwidth. Here, a sub-ring with a 5.5 m unpumped EDF based saturable absorber (SA) is also applied to induce the narrowband auto-tracking filter behavior. Based on the proposed fiber cavity induced mode-filter effect, the EDF laser can achieve the stable, narrow and wavelength-tunable output characteristics over an effective tuning range of 1568.0 to 1613.0 nm. Furthermore, the output stability, optical signal to noise ratio (OSNR), output power and laser linewidth of the laser are also performed and discussed.

A wavelength tunable linear cavity erbium-doped fiber (EDF) laser based on Sagnac loop incorporating with polarization-maintaining photonic crystal fiber (PM-PCF) was proposed and demonstrated experimentally. The Sagnac loop was composed of 0.5 m length PM-PCF, 1 × 2 optical coupler with 50:50 splitting ratio, and one polarization controller (PC). For the proposed fiber laser, the working threshold was 35 mW, the 3 m length EDF was used as gain medium, and 0.5 m length EDF was selected as saturable absorber to improve lasers stability. In the experiment, the comb filter effect was generated by Sagnac interferometer, and period was 2.52 nm. When the pump power was 150 mW, single-wavelength tunable laser output was realized within the range of 1528.73-1531.45 nm through adjusting PC, wavelength tuning interval was more than 0.58 nm, power difference was less than 3.681 dB, and signal to noise ratio (SNR) were higher than 31.101 dB. For the designed fiber laser, different groups of dualand triple-wavelength lasers output were obtained, the power difference was lower than 7.349 and 7.724 dB, and SNR was more than 31.752 and 38.623 respectively. The single-, dual-and triple-wavelength laser stability was test within 20 min, and power and wavelength fluctuation were 3.325 dB and 0.07 nm respectively.
