Differential Phase-Shift Keying Receiver Design Applied to Strong Optical Filtering

We study, via simulation and experiments, the influence of the differential phase-shift keying decoder free spectral range (FSR) when strong optical filtering is considered for the nonreturn-to-zero and return-to-zero modulation formats and show that larger FSR can improve performance.
