A complex tanh-function method is presented for constructing optical soliton solutions for quadratic–cubic nonlinear medium. In addition, an ansätze is proposed for obtaining soliton solutions of the dimensionless form of the nonlinear Schrödinger’s equation that governs the propagation of solitons through optical fibers.
