摘要

We describe a novel performance optimization method for all-optical amplitude reshaping via degenerated four-wave mixing (FWM) in highly nonlinear optical fiber.The proposed optimization method is achieved by jndiciously configuring the FWM operational condition and exploiting the nonlinear phase shift induced by self-and cross-phase modulations to properly influence the FWM conversion efficiency.Through the proposed scheme,fully functional and prevailing reshaping performance,including significant amplitude jitter suppression and extinction ratio improvement,is obtained within a single FWM stage.Results of the present theoretical calculation and numerical simulation verify the feasibility and advantages of the proposed scheme.
