“…In our experiments, the dual-pump is self-oscillated in the laser cavity where the homogeneous gain-broadening of the EDF is suppressed by nonlinear effects (FWM) in MRR at room temperature. This mechanism is the same as the cases of dual- or multi-wavelength EDF Laser realization where mode competition is overcome by nonlinear effect in the laser cavity 40 41 . By employing this novel self-locked approach, stable dual-wavelength operation is achieved and their power is equilibrated by adjusting the related attention between the two pumps using the programmable filter.…”

In this paper, we demonstrate a novel dual-pump approach to generate robust optical frequency comb with varying free spectral range (FSR) spacing in a CMOS-compatible high-Q micro-ring resonator (MRR). The frequency spacing of the comb can be tuned by an integer number FSR of the MRR freely in our dual-pump scheme. The dual pumps are self-oscillated in the laser cavity loop and their wavelengths can be tuned flexibly by programming the tunable filter embedded in the cavity. By tuning the pump wavelength, broadband OFC with the bandwidth of >180 nm and the frequency-spacing varying from 6 to 46-fold FSRs is realized at a low pump power. This approach could find potential and practical applications in many areas, such as optical metrology, optical communication, and signal processing systems, for its excellent flexibility and robustness.

“…With the advantage of a high nonlinearity of the HG-HNLF, the FWM-based intensity-dependent gain is integrated into the laser cavity to reduce the competitiveness of gain in Tm-doped fibre. The room temperature is at a range of 0,86 nm in wavelength due to 50-m HG-HNLF, 9, 22, and 36 lasing lines about 10-dB, 20-dB, and 30-dB [18]. Finally [19,20], these studies aim to develop birefringent fibres (BF) dipole and combo optical solitons along with the four-wave mixing effect (4 WM).…”

Optical fiber technologies have revolutionized telecommunication. The need for extensive transmission capability has spurred the production of fiber optics. This study aims to include a definition of XPM and FWM and how they influence the optical signal transmitted through nonlinear dispersive fibers. Consequently, Nonlinear fiber optics plays a significant role in implementing high-capacity optical networks. In this work, we evaluate the effect of XPM and FWM in fiber optics based on OptiSystem simulation results in this paper. We found the Nonlinear optics deals with the behavior of laser, Nonlinear effects in the optical fiber occurring due to nonlinear refractive index are Cross-Phase Modulation (XPM) and Four-Wave Mixing (FWM). In summary, Nonlinear effects are essential for inventing lasers, amplifiers, switching, multiplexing devices, and demultiplexers.

“…At present, several approaches have been reported to perform stable multi-wavelength generation in TDFLs [7]- [20]. These methods include, for example, the use of Sagnac loop mirrors [7], [9], [15], [16], Fabry-Perot [18] or Mach-Zehnder [8], [11], [16] interferometers, specialty optical fibers [11], [19], mode-beating filters [7], [12], and fourwave mixing techniques [10], among others [13], [17], [20]. Recently, the fiber laser community have spent its efforts to develop fiber-optic devices operating in the 2-μm region, as a consequence, new configurations of fiber components and TDFLs continue to be suggested following this research line.…”

The present manuscript experimentally demonstrates multi-wavelength generation from a thulium-doped all-fiber laser by implementing a multi-cavity Fabry-Perot filter. The filter, with a composition that relies of several silica-air and air-silica interfaces, provide a spectral reflection response that allows the laser to be operated in single-, dual-or triple-wavelength emissions by simple and clear adjustment of the polarization state. In this way, the fiber laser is capable to operate over a broad range of wavelengths extending from 1844 to 1928 nm. In addition, dual-wavelength operations are also feasible in the 1844 and 1928 nm regions, exhibiting a mode spacing of 4.41 nm and 1.62 nm, respectively. Beside this, the laser is able to switch to a sextuple-wavelength operation regime in the 1885 nm region, maintaining a minimum wavelength spacing of 1.53 nm. The laser demonstrates high wavelength stability, with variations below 60 pm at all analyzed wavelengths, and a minimum peak power fluctuation of ±2.77 dB.
