Solitons in nonlinear directional couplers with optical metamaterials by unified Riccati equation approach

The unified Riccati equation approach identifies soliton solutions to couplers in optical metamaterials. A spectrum of soliton solutions with their respective existence criteria are recovered. Both, twin-core and multiple-core couplers are studied in this work.

Solitons in nonlinear directional couplers with optical metamaterials by first integral method

This paper studies couplers in optical metamaterials with six nonlinear forms with first integral method. The algorithm yielded dark and singular optical soliton solutions. Both twin-core as well as multiple-core couplers are addressed with this scheme.

Solitons in nonlinear directional couplers with optical metamaterials by exp(− Φ(ξ))-expansion

This paper studies solitons in optical couplers that are made up from metamaterials. Twin core as well as multiple-core couplers are considered. The study is conducted by the aid of exp(− Φ(ξ))-expansion scheme for four forms of nonlinearity and they are Kerr law, power law, parabolic law and dual-power law. Singular and combo-soliton solutions are recovered from this algorithm.

Optical solitons in nonlinear directional couplers with trial function scheme

This paper obtains bright, dark and singular soliton solutions to optical couplers that appear with four forms of nonlinearity. Twin-core couplers as well as multiple-core couplers are considered.

Solitons in nonlinear directional couplers with optical metamaterials

This paper obtains bright, dark, and singular optical solitons in nonlinear directional couplers with optical metamaterials. The mathematical principle of undetermined coefficients is applied to extract these soliton solutions, with phase-matching condition. The constraint conditions for the existence of soliton solutions naturally emerge from the solutions. Both twin-core couplers and multiple-core couplers are studied in this paper.

Optical solitons in nonlinear directional couplers with G′/G-expansion scheme

This paper obtains soliton solutions in optical couplers. The governing equation is solved by the aid of G′/G-expansion scheme. There are four types of nonlinear media that are taken into consideration. These are Kerr law, power law, parabolic law, and dual-power law. There are two kinds optical couplers studied in this paper. They are twin-core couplers and multiple-core couplers, where coupling with nearest neighbors as well as coupling with all neighbors are considered. Dark and singular soliton solutions are retrieved. These soliton solutions come with constraint conditions that must hold for the solitons to exist.

Optical solitons in nonlinear directional couplers by sine–cosine function method and Bernoulli’s equation approach

This paper obtains soliton solutions to optical couplers by two methods. These are sine–cosine function method and Bernoulli’s equation approach. There are four laws that are touched upon in this paper. These are Kerr law, power law, parabolic law and dual-power law. The first integration scheme is applicable to Kerr and power laws only where bright soliton solutions are retrievable. The second tool is applicable to parabolic and dual-power laws only that leads to dark and singular solitons for these two nonlinear media.

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.
