Envelope solitons of highly dispersive and low dispersive spin waves in magnetic films (invited)

Journal of Applied Physics, 1991
Theoretical description of spin wave (SW) envelope solitons in nonlinear dispersive media with dissipation is given in the framework of a nonlinear Schrodinger equation model with relaxation term. The conditions necessary for envelope soliton observation in magnetic films (MF) and film structures are formulated.

Highly dispersive optical solitons with differential group delay for the Kerr law of self-phase modulation

Semiconductor Physics, Quantum Electronics & Optoelectronics
The paper addresses highly dispersive optical solitons with differential group delay, characterized by the Kerr law of self-phase modulation. The extended auxiliary equation approach recovers the full spectrum of solitons.

Highly dispersive energy-managed soliton fiber laser

Optics Letters
We present a 2-μm all-fiber laser in which a highly chirped fiber Bragg grating (CFBG) sets the net cavity dispersion to −100.9 ps2. Within an energy-managed laser architecture, this large anomalous dispersion enables the mode-locking of energetic and narrow-band pulses featuring: 17.8 nJ energy, 15.2 ps duration, and 0.36 nm bandwidth.

Highly dispersive optical solitons with non-local nonlinearity by F-expansion

Optik, 2019
Abstract This paper secures bright, dark, singular and various forms of highly dispersive combo optical soliton solutions when the nonlinear medium is of non-local type. The F-expansion mechanism is the integration tool. A wide range of additional solutions, including complexitons, are also listed that emerged from the scheme.

Highly dispersive optical solitons with quadratic-cubic law by F-expansion

Optik, 2019
Abstract This paper retrieves, bright, dark and singular highly dispersive optical solitons with quadratic-cubic law of nonlinearity. The F-expansion scheme is the integration algorithm adopted in the paper. There are other solutions to the model that are also recovered such as doubly periodic functions, Weierstrass elliptic functions and periodic ...
