Suppression of cross-gain modulation in SOA using RZ-DPSK modulation format

Conventional ON-OFF keyed modulation format is susceptible to cross-gain modulation in saturated semiconductor optical amplifiers (SOAs) that leads to crosstalk penalty for dense wavelength-division-multiplexing (DWDM) input signals. Differential phase-shift keying of optical pulses has virtually no...
