Abstract

We propose a simple technique for measuring the differential group delays (DGDs) between two different modes in a few-mode fiber (FMF) using an interferometric technique. We also experimentally demonstrate that the DGD between the two modes in the FMF with four modes can be successfully and simultaneously measured using the proposed technique.
