Abstract :
A simple method for detecting a signal encoded by coherence modulation without the use of any decoder interferometer is demonstrated. The technique is based on wavelength filtering of the channelled spectrum in the transmission link. To overcome this vulnerability in the scheme, more secure coherence modulation arrangements are proposed.
