Abstract
In order to study transmission characteristics of Lorentz pulses in a single-mode optical fiber, nonlinear Schrodinger equation was established from the Maxwell equation.The evolution equations for the parameters of the Lorentz pulses in single-mode optical fibers were derived by means of variational method from the modified nonlinear Schrödinger equation.Then,the restricted relations were obtained between amplitude and width, width and chirp.Analytical solution about the.width of pulse evolving on the propagation distance was obtained. The graph of the pulse width with the evolution of the transmission distance was described.The results show pulse width and the amplitude satisfy the adiabatic relation, the initial chirps will have an impact on the conformal transmission of Lorentz pulses.
