Various optical soliton for a weak fractional nonlinear Schrödinger equation with parabolic law

Abstract

In this manuscript, we study various forms of optical dromions (solitons) for a weak time fractional nonlinear Schrödinger equation (WTFNLSE) with parabolic law. We obtain various forms of solitons like as bright dromions, dromions wall, singular dromions of types 1 and 2, dark in the bright, combined dark bright solitons and periodic solution of types 1, 2 and 3 by using various ansatz approaches under some certain conditions. At the end we will also present our results graphically in different dimensions.
