| Abstract: | Transmission control using dispersion decreasing fibers with potential applications to the design of high-speed optical devices and long distance transmission of pulses is investigated based on solving the variable-coefficient nonlinear Schrödinger equation. By using Hirota's method, the analytic fundamental soliton solution of this model is obtained. In addition, according to this solution, the relevant properties and features of physical and optical interest are illustrated. Furthermore, the profiles of dispersion decreasing fibers are found to be able to control the pulse speed under certain conditions. |
