Cubic-Quartic Optical Solitons in Fiber Bragg Gratings with Dispersive Reflectivity Having Parabolic Law of Nonlinear Refractive Index by Lie Symmetry
Malik, Sandeep; Kumar, Sachin; Biswas, Anjan; Y?ld?r?m, Yakup; Moraru, Luminita; Moldovanu, Simona; Iticescu, Catalina; Alshehri, Hashim M. (MDPI, 2022-11-11)This work recovers cubic-quartic optical solitons with dispersive reflectivity in fiber Bragg gratings and parabolic law of nonlinearity. The Lie symmetry analysis first reduces the governing partial differential equations ... -
Gap Solitons in Fiber Bragg Gratings Having Polynomial Law of Nonlinear Refractive Index and Cubic�Quartic Dispersive Reflectivity by Lie Symmetry
Malik, Sandeep; Kumar, Sachin; Biswas, Anjan; Y?ld?r?m, Yakup; Moraru, Luminita; Moldovanu, Simona; Iticescu, Catalina; Moshokoa, Seithuti P.; Bibicu, Dorin; Alotaibi, Abdulaziz (MDPI, 2023-04-24)The current paper recovers cubic�quartic optical solitons in fiber Bragg gratings having polynomial law of nonlinear refractive index structures. Lie symmetry analysis is carried out, starting with the basic analysis. Then, ... -
Highly Dispersive Optical Solitons in the Absence of Self-Phase Modulation by Lie Symmetry
Malik, Sandeep; Kumar, Sachin; Biswas, Anjan; Y?ld?r?m, Yakup; Moraru, Luminita; Moldovanu, Simona; Iticescu, Catalina; Alotaibi, Abdulaziz (MDPI, 2023-04-10)The paper revisits highly dispersive optical solitons that are addressed by the aid of Lie symmetry followed by the implementation of the Riccati equation approach and the improved modified extended tanh-function approach. ...
