In this paper, the dark or topological optical 1-soliton solution of the nonlinear Schrodinger's equation is obtained. The time-dependent coefficients of the group velocity dispersion, Kerr nonlinearity and the attenuation terms are considered This leads to the constraint. relation between these coefficients for the topological solitons to exist. All what is necessary is that these time-dependent coefficients be simply Riemann integrable. (C) 2008 Elsevier B.V. All rights reserved
