Optical dark and singular solitons to the Biswas-Arshed equation in birefringent fibers without four-wave mixing

Construction of optical solitons and other families of solutions to the nonlinear Biswas-Arshed model in birefringent fibers without four-wave mixing terms

“…It is well-known [27][28][29][30][31][32][33][34][35] that Biswas-Arshed model in birefringent fibers without FWM is written in the form…”

“…To solve the Biswas-Arshed coupled system (26) and (27), in birefringent fibers without FWM, we assume that…”

“…The function Ω(x, t) is a real function denote the phase component of the soliton, while the real functions G i (ξ), (i = 1, 2) represent the shape of the pulse of the solitons. Substituting (28) and (29) along with (30) into the coupled system (26) and (27) and separating the real and imaginary parts, we have the following equations…”

“…Hence, we aim to solve Eq. (38) to extract optical solitons and other families of solutions of the Biswas-Arshed model in birefringent fibers without FWM, namely the system of equations ( 26) and (27). To this end, let us rewrite Eq.…”

Structure of optical solitons in magneto–optic waveguides with dual-power law nonlinearity using modified extended direct algebraic method

“…On the other hand, optical solitons is one of the vital areas of research in the field of nonlinear optics (Adem et al 2020;Javed et al 2020;Al Khawaja and Al-Marzoug 2020;Hari et al 2020;El-Borai et al 2017;Biswas et al 2019;Awan et al 2021;Seadawy et al 2021;Ahmed et al 2020;El-Sheikh et al 2019a, b, 2020Tahir and Awan 2020;Yldrm 2019Yldrm , 2021Liu et al 2016Liu et al , 2017aLiu et al , b, c, 2018Yan et al 2020;Fan et al 2019;Wang et al 2019). Magneto-optic wave guides can help to reduce solitons clutter, to solve the internet bandwidth issue and other such injurious features (Biswas 2004;Tien 1971).…”
