Abstract
Optical time division multiplexing (OTDM) is an efficient way to increase the transmission capacity of fiber links [1]. In such systems all-optical demultiplexing is a key issue. Several demultiplexing schemes have been reported: demultiplexing using a nonlinear optical loop mirror (NOLM), four- wave-mixing (FWM) besides optical- and electrical modulation of semiconductor optical amplifiers (SOA). Both fiber and SOA based NOLM and FWM schemes have been investigated, and very high speed demultiplexing has been achieved [1-4].
