“…In recent years, tunable erbium-doped fiber lasers (EDFLs) have become one of the preferred light sources for a series of applications, such as optical communication, fiber sensing, interferometers and wavelength division multiplexing (WDM) [1][2][3], due to their excellent properties in the wide tuning range, good stability, good beam quality and low cost. Although erbium-doped fiber (EDF) has a large uniform broadening characteristic at room temperature, which leads to serious mode competition [4], making it difficult for EDFL to obtain a stable multi-wavelength excitation, the high gain spectrum of EDF in the C-band [5] enables it to have good switchable and tunable performance in a wide wavelength range.…”

In this paper, a new type of widely tunable and switchable multi-wavelength erbium-doped fiber laser based on a Sagnac-like loop embedded in Lyot filter is proposed. The nonlinear polarization rotation effect is obtained by adjusting two polarization controllers (PCs). The polarization-dependent isolator and the Sagnac-like loop are used as the basic structure to realize the wide tuning and wavelength switching in C-band. Compared with the traditional Lyot filter, the Sagnac-like loop is used to replace the segment of polarization-maintaining fiber, and a more uniform comb spectrum can be obtained by this filter. The tunable and switchable wavelengths can be achieved by adjusting the PCs based on the nonlinear effect of the loop. The laser can emit single-, dual-, triple-, quad- and quintuple-wavelengths. The optical signal-to-noise ratios all exceed 43 dB. It can also be adjusted to partial wavelength intervals for quad-wavelength and quintuple-wavelength. The tuning range can reach the full range of the C-band, and the laser efficiency can reach the practical application standard. It can be applied to some precision instruments and equipment.

A tunable wavelength-selective fiber Bragg grating (FBG) filter was demonstrated in an erbium-doped fiber ring laser (EDFRL) configuration to achieve a stable and tunable dual-wavelength laser source. The tuning method was based on a thermo-optic effect of a single FBG divided into two segments by two identical coils. Using this coil heater, we showed a continuous wavelength spacing of dual-wavelength output from 0.25 to 5.5 nm. Furthermore, each wavelength could be independently changed during lasing operation without thermal crosstalk between adjacent channels.

A simple multi-wavelength laser source using, an erbium doped fiber (EDF) as a gain medium is proposed. The source is terminated by a chirped fiber Bragg grating (CFBG) on one side and cascaded FBGs on the other side. Different apodization profiles for the FBG are analyzed to improve the lasing wavelengths selectivity. The Blackman profile is found to be the best to reduce the reflection spectrum sidelobes with a maximum reflectivity of 99%.
