Abstract
Dark solitons are widely studied because of their unique characteristics in inhomogeneous optical fibers . A fourth-order nonlinear Schrödinger equation is studied in this paper. Dark soliton solutions are obtained by the Hirota method. With some suitable functions of the variable coefficients, interactions among dark solitons are presented, and their interaction properties are analyzed. Results have some potentially applications in optical fibers and the design of optical switches.
