Dispersion compensation in coherence domain multiplexed communications systems

Coherence Domain Multiplexing (CDM) is a point-to-point communications system using parallel input to encode bits in coherence-modulated pulse packets. Interferometric detection decodes the bits in parallel, and automatically compensates for fiber linear dispersion. This is similar to existing Coherent CDMA systems, except that direct encoding and detection of the bits in the pulse train eliminates the wasted bandwidth inherent in optical orthogonal code systems. In this paper we demonstrate dispersion compensation in coherence multiplexed systems by transmitting three 100 fs signal pulses and a reference pulse in a packet through an optical fiber
