Temporal Solitons of Modified Complex Ginzberg Landau Equation

“…Investigations on nonlinear wave equations have been a fascinating topic both for mathematicians and physicists because of their numerous application potential in diverse areas [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][29][30][31][32][33]. In particular, the nonlinear Schrödinger equation (NLSE) and the complex Ginzburg Landau equation (CGLE) and their modified versions have drawn tremendous attention during last three decades [2][3][4][5][6][7][8].…”

“…In particular, the nonlinear Schrödinger equation (NLSE) and the complex Ginzburg Landau equation (CGLE) and their modified versions have drawn tremendous attention during last three decades [2][3][4][5][6][7][8]. These equations describe a variety of physical phenomena in plasmas, optical waveguides and fibers, Bose Einstein condensation, phase transitions, bimolecule dynamics, open flow motions, spatially extended nonequilibrium systems etc [1].…”

“…Large volume of analytical investigations have been carried out to find the soliton solutions of these equations which are localized waves that show particle like behaviour i.e., their forms are preserved in space or in time or both in space and time resulting in respectively spatial, temporal or spatiotemporal solitons. Finding soliton solutions of nonlinear wave equations representing various physical phenomena have been the major thrust of theoretical research [2][3][4][5][6][7][8][9][10]. Nonlinear equations representing Hamiltonian systems are not always integrable.…”

Timing Shift of Optical Pulses Due to Inter-Channel Cross-Talk

“…In the modern times in telecommunications systems, the usage of optical fibers is a good transmission medium [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20].…”

Doubly Periodic Solution for Nonlinear Schrödinger’s Equation With Higher Order Polynomial Law Nonlinearity

“…It appears in many applied fields like Fluid Dynamics, Nonlinear Optics, Plasma Physics and Protein Chemistry. The NLSE that is going to be studied in this paper is given by [1][2][3][4][5][6][7][8][9][10][11][12].…”
