Abstract :

A numerical solution of the equations for multi–lobe soliton has been performed using a Gaussian array function. The linear and nonlinear parts of the index potential of the modulated periodic lattice is investigated numerically. Single–lobe and dipole solitons are formed with a family of small single solitons. The family soliton and solitons of the family are compared with numerical values for both the cases.
