“…In recent years, erbium-doped fiber lasers (EDFLs) have attracted significant attention in the field of optical fiber lasers [1] and have been widely used in infrared detection, optical radar, and dense wavelength division multiplexer (DWDM). [2,3] In the EDFL research field, mode-lock lasers, [4] tunable wavelength lasers, [5] Raman lasers, [6] and singlefrequency [7] lasers are important research interests owing to their different applications. Multiwavelength tunable EDFLs have many advantages such as a large laser number, narrow linewidth, high stability, wide tunable laser wavelength, and high optical signal-to-noise ratio (SNR), [8,9] thus, they have been studied by many scientific research institutions.…”

In this study, a multiwavelength tunable ring-cavity erbium-doped fiber laser (EDFL) based on a Lyot filter was presented. For the proposed Lyot filter, a comb filter consisting of an EDF-polarization-maintaining fiber (EDF-PMF), a polarization controller (PC), and a circulator with four ports was used to suppress the mode competition. The light transmission direction was guaranteed by the circulator. For the proposed fiber laser, tunable single, dual, triple, quadruple, quintuple, sextuple, and septuple wavelengths were realized. A single-wavelength laser output with an optical signal-to-noise ratio (SNR) of up to 30.56 dB was realized, and a tuning range of 1590.54 to 1599.54 nm was achieved by tuning the PC. The stability of the single, dual, triple and quadruple-wavelength center power fluctuations was less than 0.05, 0.98, 5.07, and 7.71 dB respectively. When the laser was operated in the multiwavelength condition, the SNR was more than 20.97 dB. The proposed erbium-doped fiber laser is suitable for fiber-sensing system applications.

“…[52] Besides, a variable-coefficient version of Equation (1) has been investigated via the Hirota bilinear method and symbolic computation. [53,54] However, Equation 1has not been reduced into a set of the (1+1)-dimensional equations for constructing its groupinvariant solutions. Lie symmetry groups of Equation 1, which can be used for adjusting the amplitudes, widths, velocities, and propagation directions of the nonlinear spin waves in the semiclassical continuum Heisenberg system, have not been investigated.…”

Nonlinear spin excitations in ferromagnetic spin chains are studied for spintronic and magnetic devices including magnetic-field sensors and for high-density data storage. Here, (2+1)-dimensional nonlinear Schrödinger equation is investigated, which describes the nonlinear spin dynamics for a Heisenberg ferromagnetic spin chain. Lie point symmetry generators and Lie symmetry groups of that equation are derived. Lie symmetry groups are related to the time, space, scale, rotation transformations, and Galilean boosts of that equation. Certain solutions, which are associated with the known solutions, are constructed. Based on the Lie symmetry generators, the reduced systems of such an equation are obtained. Based on the polynomial expansion and through one of the reduced systems, group-invariant solutions are constructed. Soliton-type group-invariant solutions are graphically investigated and effects of the magnetic coupling coefficients, that is, α 1 , α 2 , α 3 , and α 4 , on the soliton's amplitude, width, and velocity are discussed. It is seen that α 1 , α 2 , α 3 , and α 4 have no influence on the soliton's amplitude, but can affect the soliton's velocity and width. Lax pair and conservation laws of such an equation are derived.
