Optical solitons in nonlinear directional couplers with spatio-temporal dispersion

This paper addresses solitons in nonlinear directional couplers in non-Kerr law media, with spatio-temporal dispersion. Both twin-core couplers as well as multiple-core couplers are studied. The nonlinearities studied are Kerr law, power law, parabolic law, dual-power law and log law. Bright, dark and singular soliton solutions of the governing equation are studied.

Dispersive optical solitons with Schrodinger-Hirota equation

The dynamics of dispersive optical solitons, modeled by Schrodinger–Hirota equation, are studied in this paper. Bright, dark and singular optical soliton solutions to this model are obtained in presence of perturbation terms that are considered with full nonlinearity. Soliton perturbation theory is also applied to retrieve adiabatic parameter dynamics of bright solitons. Optical soliton cooling is also studied. Finally, exact bright, dark and singular solitons are addressed for birefringent fibers with perturbation terms included.

Optical solitons in DWDM system with spatio-temporal dispersion

This paper obtains bright, dark and singular soliton solutions to dense wavelength division multiplexed (DWDM) system, with spatio-temporal dispersion. There are two types of nonlinear media that are considered and they are Kerr law and parabolic law. Four integration algorithms are applied to retrieve these solitons. They are G′/G-expansion scheme, extended tanh function approach, Kudryashovs algorithm and finally the ansatz method. The results follow with respective constraints that guarantees the existence of solitons.

Optical Solitons in Magneto-optic Waveguides with Spatio-temporal Dispersion

Abstract This paper obtains the exact solution for solitons propagating through magneto-optic waveguides. There are three forms of nonlinear media that are considered. They are Kerr law, power law and log-law nonlinearity. The ansatz approach retrieves bright, dark as well as singular soliton solutions. There are several constraint conditions that needs to be in place for the solitons and Gaussons to exist.

Bright and singular solitons in quadratic nonlinear media

This paper addresses the dynamics of bright and singular optical solitons in quadratic nonlinear media. The ansatz approach is the tool of integration of this model. The 1-soliton solution is obtained and the constraint conditions fall out during the course of derivation of the soliton solution.
