Abstract

Sagnac interferometric loops with a semiconductor optical amplifiers (SOA) have found important applications for optical signal processing and communication networks. We derive a new description of the transmission of an SOAbased Sagnac loop by including the influence of loop birefringence. Based on this new description, we theoretically analyze and experimentally demonstrate NRZ wavelength conversion using a Sagnac loop with an SOA at asymmetric position. We also show that the converted signal with an SOA-based Sagnac loop has lower pattern dependent effect and smaller power penalty compared with the converted signal using cross gain modulation effect.
