Abstract :
A novel method for de-multiplexing a differential phase shift keying (DPSK) optical time-domain multiplexed signal and simultaneously demodulating the de-multiplexed channel is proposed and numerically investigated. The scheme is based on the combination of four wave mixing wavelength conversion and wavelength-dependant group delay.
