Highly Dispersive Optical Solitons in the Absence of Self-Phase Modulation by Lie Symmetry

Symmetry, 2023
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. The soliton solutions are recovered and classified.

Highly dispersive optical solitons with polarization–mode dispersion for non–local law of self–phase modulation

Journal of Optics
AbstractThe current paper recovers a variety of highly dispersive optical solitons with non–local form of self–phase modulation structure and having polarization–mode dispersion. Two integration approaches have made this retrieval successful. The soliton solutions are enlisted and presented with the parameter constraints that ensures their existence. A

Highly dispersive optical solitons with polarization-mode dispersion for polynomial law of self-phase modulation

Journal of Optics
AbstractThis paper recovers highly dispersive 1-soliton solutions with differential group delay and having polynomial law of self-phase modulation structure. Two integration approaches have made this retrieval possible. They are the extended auxiliary equation method and Kudryashov’s algorithm.

HIGHLY DISPERSIVE OPTICAL SOLITONS WITH QUADRATIC-CUBIC NONLINEAR REFRACTIVE INDEX BY LIE SYMMETRY

Journal of Applied Analysis & Computation
Summary: This paper addresses highly dispersive optical solitons with quadratic-cubic nonlinear form of self-phase modulation. Lie symmetry analysis reduced the governing model to an ordinary differential equation which was further analyzed using two approaches.

Highly Dispersive Optical Gap Solitons with Kundu-Eckhaus Equation Having Multiplicative White Noise

Contemporary Mathematics
This paper explores the dynamics of highly dispersive gap solitons within the framework of the Kundu-Eckhaus equation, augmented by the inclusion of multiplicative white noise in the Itô sense, a novel addition to the model. Two integration schemes, the extended simplest equation approach and the generalized Riccati equation mapping scheme, are ...

Soliton shedding from Airy pulses in a highly dispersive and nonlinear medium [PDF]

Journal of the Optical Society of America B, 2021
We present a numerical investigation of the propagation dynamics of a truncated Airy pulse in a highly dispersive and nonlinear medium by employing the split-step Fourier transform method and look, in particular, into the effects of fourth-order dispersion (FOD) and cubic-quintic-septic nonlinearity on pulse evolution.
