All-Optical 2R Regeneration of BPSK and QPSK Data using a 90° Optical Hybrid and Integrated SOA-MZI Wavelength Converter Pairs

Abstract

We demonstrate all-optical 2R regeneration with a 90° optical hybrid and integrated MZI-SOA pairs for 10 Gb/s BPSK and 20 Gb/s QPSK with negative power penalty. Power penalty and OSNR improvements of 7 dB and 5 dB are shown with additive ASE noise.
