Abstract :
A novel approach to demultiplexing in subcarrier optical systems is described. The technique of optical prefiltering microwave subcarriers from an optical carrier, enabling direct detection of baseband signals, is proposed. The technique is experimentally verified by demultiplexing two 10 Mbit/s channels.
