摘要：

In this paper, we find the dipole soliton (dark-in-the bright) for higher order nonlinear Schrodinger equation (HNLSE) with kerr law. This equation represents the propagation of a nonlinear ultrashort laser pulse in the optical fiber. We use the ansatz method of Choudhuri and Porsezian to find the solitary wave solution, which is combination of product of dark and bright solitary waves. We also find single Gausson soliton solution for (HNLSE) with log law nonlinearity described in optical nano fibers. (C) 2017 Elsevier Ltd. All rights reserved.
