Presidential Young Investigator Award: Nonlinear Phenomena in Optical Fibers and Semiconductor Lasers

PI获得了总统青年研究员奖，并将他的研究描述如下：该项目的目标是研究光纤和半导体激光器的非线性动力学。光纤的强度相关折射率导致了光束在光纤中偏振态的一定不稳定性。我们计划扩展我们对这一现象的理论研究，包括群速度色散、耗散、光纤微扰和反向传播脉冲几何。最近关于调制半导体激光器中混沌的工作将扩展到半导体激光器阵列的动力学。理论研究的目的将是阐明导致这些激光器时空混沌输出的参数范围。还将研究通过注入信号实现的稳定。这位少年侦探获得了总统青年调查员奖。他将对半导体激光器及其传输所用光纤的非线性动力学行为进行研究。将对半导体激光器中的混沌行为进行理论研究，并研究稳定激光输出的方法。

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.
