摘要

Abstract

To suppress the dispersion effect, an improved scheme was proposed for Mach-Zehnder interferometer (MZI) based interleaver. The device consists of an MZI, a fiber loop (FL), and a phase shifter inserted in FL. The introduction of π phase shifter into FL dramatically suppresses the dispersion effect.Then the transmission response remains square-like shape, with low frequency deviation and high extinction ratio. Moreover, the lower frequency deviation is achieved by reducing the dispersion coefficient. For 100GHz-spacing interleaver, the 0.08nm deviation is reduced to 0.02nm by replacing G. 652 with G.655.
