Abstract :
Summary form only given. All-optical time-division demultiplexing (TDM) is one of the most fundamental functions in future Tbit/s all-optical networks. This paper proposes a simple polarisation independent (PI) all-optical TDM demultiplexer that utilizes the ultrafast four-wave mixing (FWM) process of both TE and TM modes in a semiconductor laser amplifier (SLA) in which input pump and signal pulses are deliberately depolarized to suppress polarization coupling.
