Two nonel configurations of OADMs based on MZIs with FBGs

摘要

Two novel kinds of reconfigurable multi-path OADM structures based on MZI with FBGs are proposed in this paper. These novel OADM is determiend by adding/dropping different wavelengths making use of optical switches and tunable FBGs. There are very low incoherent crosstalk and no any coherent crosstalk in these novel OADMs in theory. so very large scaling of the network which is composed of the novel OADMs is demosntrated in the paper.
