All-optical 2R regeneration of BPSK and QPSK data using a 90° optical hybrid and integrated SOA-MZI wavelength converter pairs

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.
