Simultaneously all-optical inverted and noninverted wavelength conversion employing SOA-based Sagnac interferometer

摘要

This paper have successfully demonstrated an all-optical wavelength conversion scheme for all-speed return-to-zero (RZ) format data input by using a Sagnac interferometer based on semiconductor optical amplifier (SOA). The attractive issue of the proposed method is that the converted signal can be obtained simultaneously with inverted and noninverted wavelength conversion signals.
