Rational Solitons in the Gardner-Like Models

Fluids, 2022
Rational solutions of nonlinear evolution equations are considered in the literature as a mathematical image of rogue waves, which are anomalously large waves that occur for a short time. In this work, bounded rational solutions of Gardner-type equations

Generation of a Train of Ultrashort Pulses Near-Infrared Regime in a Tapered Photonic Crystal Fiber Using Raised-Cosine Pulses

IEEE Photonics Journal, 2012
We consider an optical pulse propagating in a tapered photonic crystal fiber (PCF) wherein dispersion as well as nonlinearity varies along the propagation direction.

Real-time dynamics of soliton collision in a bound-state soliton fiber laser

Nanophotonics, 2019
We experimentally investigated the soliton collisions between soliton molecules and deuterogenic solitons spontaneously generated on the continuous wave (cw) noise background in an ultrafast erbium-doped fiber laser mode locked with MoS2 saturable ...

Graphdiyne-decorated microfiber based soliton and noise-like pulse generation

Nanophotonics, 2021
Graphdiyne has an inborn band gap energy, where the minimal band gap is about from 0.46 to 1.22 eV, which shows great potential in ultrafast laser generation.

Multi loop soliton solutions and their interactions in the Degasperis-Procesi equation

, 2012
In this article, we construct loop soliton solutions and mixed soliton - loop soliton solution for the Degasperis-Procesi equation. To explore these solutions we adopt the procedure given by Matsuno.

Scattering of Solitons and Dark Solitons by Potential Walls in the Nonlinear Schroedinger Equation [PDF]

, 2004
Scattering of solitons and dark solitons by potential walls is studied in the nonlinear Schroedinger equation under various conditions. We investigate the conditions under which solitons are split into two solitons at the potential wall.
