The PI has received a Presidential Young Investigator award and            describes his research as follows:  The goal of this project is to              study the nonlinear dynamics of optical fibers and of semiconductor             lasers.  The intensity-dependent refractive index of optical fibers             leads to certain instabilities of the polarization state of a light             beam in the fiber.  We plan to extend our theoretical studies of this           phenomenon to include group velocity dispersion, dissipation, fiber             perturbations, and counter-propagating pulse geometries.  Recent work           on chaos in modulated semiconductor lasers will be extended to the              dynamics of semiconductor laser arrays.  Theoretical studies will be            aimed at elucidating parameter ranges that lead to a spatio-temporal            chaotic output of these lasers.  Stabilization by means of an injected          signal will also be studied.                                                         This PI has received a Presidential Young Investigator award.  He          will conduct research on the nonlinear dynamical behavior of                    semiconductor lasers and of the optical fibers used for their                   transmission.  Theoretical studies of chaotic behavior in                       semiconductor lasers will be conducted and methods to stabilize the             laser output will be investigated.
