Dispersion Effects in Nonlinear Light Propagation in 1-D Fiber Gratings

摘要

This report results from a contract tasking Universidad Politecnica of Madrid as follows: The contractor will investigate the use of the so-called nonlinear coupled mode equations (NLCME) to obtain approximate solutions of Maxwells equations for light propagation in periodic optical fiber structures. In particular, one class of solutions called 'Gap Solitons.' exhibit the ability to propagate at any speed from zero to the local speed of light, and offer great promise for various optical storage and buffer devices. This project will test the accuracy of the NLCME approximation for the propagation of gap solitons in optical fibers with material dispersion, by comparing NLCME solutions with exact solutions of the Maxwell's equations.
