Abstract

Dispersion and dispersion slope management is a problem for LEAF fiber, because LEAF fiber has a low dispersion but a significantly high relative dispersion slope. This article demonstrates a design of dispersion and dispersion slope compensator for LEAF fiber in WDM systems. It can compensate dispersion and dispersion slope respectively by combining broadband nonchannelized linear chirped fiber Bragg grating and a pair of nonlinear chirped fiber Bragg gratings, which can be inversely cascaded in a four-port optical circulator. The design can effectively improve dispersion linearity and increase dispersion matching ability of compensator, and a numerical experiment of compensating a 50-kmlong LEAF fiber in WDM system proves the feasibility of this approach.
