Abstract

We present an ultrahigh-speed optical demultiplexing concept based on optical blue-shift filtering in a quantum-dot semiconductor optical amplifier (QD-SOA). Using a simple scheme, a QD-SOA and an optical bandpass filter, we have successfully achieved error-free operations at 40Gbit/s on all the extracted tributaries from an aggregated traffic at 320Gbit/s.
