Pump Linewidth Requirements for Processing Dispersion-Altered DQPSK Signals using FWM

We report on a potentially deleterious issue regarding the four-wave mixing based processing of dispersion-altered signals. We estimate the baudrate-dependent pump linewidth tolerances by calculating the extra optical signal to noise ratio (OSNR) penalty with respect to the propagation distance. We...
