“…As a result, optical fiber lasers have captured the interest of researchers due to their versatile applications in commercial, industrial, medical, and military. Different techniques have been implemented to design optical fiber lasers, such as mode-locked, single-wavelength continuous wave, multiwavelength, dual-wavelength, and Q-switched lasers [1][2][3][4]. The multiwavelength fiber lasers have broadly contributed to developing technologies like optical fiber sensors, high-speed communication, 5 G networks, spectroscopy, and optical instrument testing [5][6][7][8].…”

In this work, a multiwavelength thulium-doped fluoride fiber laser (TDFFL) has been reported for S-band region using the Michelson interferometer as an optical filter. Michelson interferometer was utilized as a comb-like filter, whereas dispersion-compensated fiber (DCF) of 10 km length was used to increase the number of lasing lines and reduce mode competition. Approximately, 61 lasing lines were achieved with a signal-to-noise ratio (SNR) of 40 dB in the wavelength region from 1501.36 to 1505.52 nm within 10 dB of maximum power. The stability of multiwavelength fiber laser was also recorded for the time duration of two hours, and it was found that all lasing lines were stable and equally spaced at the free spectral range (FSR) of 0.07 nm. The variation in optical power was less than 0.5 dB, however the wavelength shift was about 0.01 nm. Tunability of multiwavelength laser has also been observed up to the broader transmission span of 57 nm by incorporating the tunable band pass filter (TBPF). Moreover, FSR was observed to be tunable within the range of 0.02 to 0.14 nm by using the optical delay line (ODL) with a Michelson interferometer. Additionally, the proposed laser can generate frequency signals from 2.65 GHz to 18.54 GHz according to the obtained range of FSR.

“…Additionally, the SMF may introduce dispersion effects, which can influence the laser's pulse duration, chirp, or spectral width [21]. However, the specific impact of adding an SMF to a Brillouin fiber laser depends on factors like the SMF's properties, laser cavity design, and intended application [22]. Careful consideration and optimization are necessary to achieve the desired performance enhancements or modifications [23].…”

Using erbium-doped fiber, a steady Q-switched erbium-doped laser (EDFL) was successfully demonstrated. With a 150 m of Single Mode Fiber to generate the Brillouin Fiber Laser and increase the non-linearity inside the cavity. In the absence of a Brillouin pump, a compact Brillouin fiber laser (BFL) is realized by combining an Erbium Doped Fiber (EDF) and a Single Mode Fiber (SMF), which serve as both the Brillouin and linear gain media. It is accomplished by self-Brillouin production in a laser cavity from 4.5 m of EDF and 150 m of SMF with strong nonlinearity. The SMF inside the ring cavity was used to generate self-generating BFL. The BFL in the linear cavity produced more Brillouin stokes at a lower pump threshold. In the experiments, the average of spacing is 0.088 nm was generated at the EDF pump power of 93.468 to 259.493 mW for the 150 m of SMF. This compact BFL has total cavity length (160.34 m). Eventually, this is the most recent gain medium length recorded for Brillouin erbium fiber laser production without the use of a Brillouin pump.

“…Such techniques limit tunability range due to EDFA self-lasing and restrict the number of comb lines at low operating power [9]- [13], [19], [20]. Although the limitations of fixed line-spacing can be eliminated by utilizing multi-Brillouin-spacing based dual ring configuration, it suffers from a limited number of comb lines [16], [21]- [24]. Thus, the SBS process is often implemented in conjunction with nondegenerate FWM to achieve a broadband OFC source with excellent tunability in line spacing.…”

In this paper, we experimentally demonstrate a lowpower, broadband, and narrow linewidth SBS-FWM OFC with tunable line spacing of 50 to 600 GHz. The SBS-FWM OFC spans a bandwidth of ≈100 nm over the C+L-band region using ≈15 dBm pump power. The OFC is obtained by cascaded FWM process in highly nonlinear fiber (HNLF), seeded by SBS pumps in an all-fiber ring cavity setup. The linewidth of the SBS-FWM comb lines is measured to be ≈20 MHz which is largely determined by the SBS pump properties. By using the optical Vernier effect, the linewidth of comb lines is reduced by a factor of more than 2000 to below 20 kHz. We utilize the SBS-FWM OFC to study the performance of binary and 4-PAM transmission at 1 and 10 Gbps in a back-to-back (B2B) setup. The side-modes caused by the FP-cavity, formed by the HNLF modules in the ring cavity in our setup, affects the performance of the B2B transmission of PAM system.
