Optical dromions with polarization–mode dispersion having parabolic law of self–phase modulation with multiplicative white noise

Abstract

This article studies optical dromions with spatio–temporal dispersion having parabolic law of nonlinear refractive index change in presence of white noise. Two integration approaches reveal the dromion solutions. They are the extended auxiliary equation approach and the generalized projective Riccati equation scheme. A wide spectrum of dromion solution structures have been revealed from such algorithms. The parameter constraints are also enlisted for these dromions to exist.
