Chirped solitary waves of the perturbed chen–lee–liu equation and modulation instability in optical monomode fibres
Houwe, Alphonse; Abbagari, Souleymanou; Almohsen, Bandar; Betchewe, Gambo; İnç, Mustafa; Doka, Serge Yamigno (Springer, 05.2021)In this paper, we show out the chirped and the corresponding chirp with their stability to the perturbed Chen–Lee–Liu equation with self-phase modulation and nonlinear dispersions. By employing the traveling-wave technique, ... -
Effects of ellipticity angle on soliton solutions and modulation instability spectra in two-core birefringent optical fibers
Dépélair, Bienvenue; Douvagaï; Houwe, Alphonse; Betchewe, Gambo; İnç, Mustafa; Doka, Serge Yamigno (Optical and Quantum Electronics, 06.2021)In this paper, we investigate a coupled nonlinear Schrodinger equation which describes the propagation the propagation of optical signal in a two core optical fiber. A rich variety of various types of solitary wave solutions ... -
Envelope solitons of the nonlinear discrete vertical dust grain oscillation in dusty plasma crystals
Houwe, Alphonse; Abbagari, Souleymanou; İnç, Mustafa; Betchewe, Gambo; Doka, Serge Yamigno; Crepin, Kofane Timoleon (Elsevier, 02.2022)The paper concerns envelope soliton propagating through the nonlinear transverse dust grain displacement in dusty plasma crystals. The work found its motivation from the recent paper of the authors [7]. To reach the goal ... -
Optical soliton and weierstrass elliptic function management to parabolic law nonlinear directional couplers and modulation instability spectra
Houwe, Alphonse; Abbagari, Souleymanou; Nestor, Savaissou; İnç, Mustafa; Hashemi, Mir Sajjad; Betchewe, Gambo; Doka, Serge Yamigno (Springer Nature, 2021)Abstract This paper shows out optical soliton solutions of the twin-core couplers with parabolic law nonlinearity with optical metamaterials parameters. It is used the improved new sub-ODE method (SOM) to found dark optical ... -
Solitary waves and modulation instability with the infuence of fractional derivative order in nonlinear left‑handed transmission line
Ahmadou, Djidere; Alphonse, Houwe; Justin, Mibaile; Betchewe, Gambo; Serge, Doka Yamigno; Crepin, Kofane Timoleon; İnç, Mustafa (Springer Nature, 2021)Abstract The resolution of the reduced fractional nonlinear Schrödinger equation obtained from the model describing the wave propagation in the left-handed nonlinear transmission line presented by Djidere et al recently, ... -
Sundry optical solitons and modulational instability in sasa-satsuma model
Justin, Mibaile; David, Vroumsia; Shahen, Nur Hasan Mahmud; Sylvere, Azakine Sindanne; Rezazadeh, Hadi; İnç, Mustafa; Betchewe, Gambo; Doka, Serge Yamigno (Springer, 02.2022)In this paper, we fnd new soliton solutions of the Sasa-Satsuma equation according to the Sardar sub-equation scheme. Diferent forms of soliton solutions, including the optical dark, optical bright, and optical singular ...
