Time Advancement and Pulse Distort of Stimulated Brillouin Scattering Fast Light High Nonlinear Optical Fibers
摘要
Abstract
Based on the three coupled wave equations of stimulated Brillouin scattering and under the condition of small-signal model, the time advancement and pulse distort of fast light in high nonlinear optical fiber were investigated.The results indicate that the time advancement linearly increases and pulse compression becomes larger with the increasing of the input signal power and the transmission distance in optical fiber.Under the same condition, the time advancement occurred in high nonlinear optical fiber is larger than that in single mode fibers, and the maximum advancement of 203 ns as well as small pulse distort are achieved in high nonlinear fiber at the signal power of 50 mW and the fiber length of 50 m.The efficiency of time advancement of fast light in high nonlinear fiber is significantly improved and the pulse deformation is obviously decreased.The research results provide reference for the implementation and application of fast light.关键词
