80Gbit/s return-to-zero DPSK regeneration using CW-driven SOA-MZI

80 Gbit/s RZ-DPSK regeneration with wide-range of random phase and amplitude noise is demonstrated numerically. RZ-DPSK is converted to modulated-CW that reconstructs clean data (differential phase-error = 4
^o
) using SOA-MZI. BER shows 4.8 dB OSNR improvement at 10
^-9
.
