“…To realize switchable output in TDFLs, different wavelength switchable mechanisms have been proposed-for example, an inline acousto-optic tunable bandpass filter [26], a digital micromirror array [27], a diffraction grating [28], polarization-dependent loss (PDL) [29], changing the temperature [30], applying strain [31], and enforcing axial misalignment [32]. It should be noted that digital micromirror arrays and diffraction gratings are expensive, making such TDFLs costly.…”

A thulium-doped fiber laser (TDFL) with switchable single-wavelength output was proposed and experimentally constructed, and its output characteristics were investigated. The central wavelengths were 1940.52 nm and 2048.04 nm, defined by a superimposed uniform fiber Bragg grating (SI-UFBG) with reflectivity larger than 92%. Switchable output was successfully achieved by using polarization-dependent loss, with the help of a drop-in polarization controller and an in-line polarizer. For both output wavelengths, optical signal-to-noise ratios larger than 80 dB were achieved. Maximum fluctuations of the central wavelengths of 1940.52 nm and 2048.02 nm under 60 min were, respectively, 0.04 nm and 0.01 nm. Maximum fluctuations of output power for the same wavelengths over the same time period were, respectively, 1.09 dB and 0.12 dB. Maximum output powers of 215.12 mW and 155.53 mW were achieved for the respective output wavelengths of 1940.52 nm and 2048.02 nm. Moreover, a tuning range of ∼2 nm was realized by enforcing a strain on the SI-UFBG. The proposed TDFL may be applied in laser medicine and free-space-related applications.

“…To date, various TDFLs have been proposed, including the TDFL with switchable output [12], [13], TDFL with single-longitudinal-mode operation [14], [15], mode-locked TDFL [16], [17] and high power TDFL [18]. The TDFL with switchable output is extensively used in optical fiber sensing and wavelength routing networks due to its flexible lasing performance.…”

In this article, a precisely controlled, switchable thulium-doped fiber laser (TDFL) with high optical signal-to-noise ratio (OSNR) is proposed and demonstrated. A home-made multimode fiber Bragg grating (MMFBG) with multireflection peaks was used as an optical filter to select the desired lasing channel. Using a manually controlled fusion splicer, the axial misalignment was applied between the single mode fiber and the MMFBG to switch the output wavelength. In the experiment, the number of switchable lasing lines was up to 12, and the fluctuation of the center wavelength and output power was less than 0.03 nm and 0.67 dB, respectively. A maximum slope efficiency of 1.3% was obtained when the axial misalignment was 0 μm, and the OSNR was higher than 65 dB. In addition, the proposed fiber laser was used as an optical fiber laser sensor to quantify the strain applied on the MMFBG, and a sensitivity of 1.16 pm/με was obtained.

“…To switch the wavelength, wavelength-selection and competitioninhibition mechanisms are needed. The wavelength can be selected with filters, such as the Mach-Zehnder interferometer [17] , cascaded Sagnac loop [18] , fiber-based Lyot filter [19] , micro fiber-optic Fabry-Perot interferometer [20] , few-mode fiber-based interferometer [21][22][23] and fiber Bragg grating (FBG) filters [7,24] . In particular, the FBG filter has been a good choice due to its simple structure, small size, and flexible tunability [25][26][27] .…”

A wavelength-switchable single-longitudinal-mode thulium-doped fiber laser using a sampled fiber Bragg grating is proposed in this study. The laser can be switched between three single-wavelength and three dual-wavelength modes of operation. For the single-wavelength mode of operation, the maximum power and wavelength fluctuations in 50 min were ±0.404 dB and ±0.01 nm, and the linewidths at three wavelengths were 0.39, 1.88, and 0.89 kHz, respectively. For the dual-wavelength mode of operation, the maximum power and wavelength fluctuations in 20 min were ±0.926 dB and ±0.03 nm, respectively. The proposed thulium-doped fiber laser will find useful application in optical communication and free-space optical detection and sensing.INDEX TERMS thulium-doped fiber laser, wavelength-switchable, narrow linewidth, sampled fiber Bragg grating.
