Multi Gaussian Breather Solitons in Diffraction Managed Nonlinear Optical Media
Naveen Gupta
Theoretical investigation on existence of multi Gaussian (M.G) breather solitons in diffraction managed optical media with cubic-quintic nonlinearity in their index of re-fraction has been presented. Semi analytic solution of the nonlinear Schrodinger wave equation (NSWE) for the field of optical beam beam has been obtained by making use of variational theory based on hamiltonian formulation. Particularly the evolutions of transverse dimensions and axial phase of the optical beam during its propagation have been investigated in detail. Formation of stable spatial optical soliton resulting from the balance between diffraction broadening and self focusing has been also investigated.
