All-optical 2R regeneration based on interferometricstructure incorporating semiconductor optical amplifiers

Abstract

All-optical 2R regeneration in an SOA-based interferometric Michelson structure using a novel technique is experimentally demonstrated. An output extinction ratio of ~10 dB is measured for an input extinction ratio of 6 dB and a noise suppression capability of ~4.5 dB is obtained, clearly demonstrating the feasibility of this technique.
