Abstract

We propose a point-to-point or single-ended communications technique based on single-mode optical fibers that uses all-optical pulse multiplexing at the transmitter and coherent optical correlation at the receiver. This technique shows potential for application to secure untappable communications, fiber local-area networks, and optical ranging in the presence of a strong white-light background. The system can employ a low-coherence source, is insensitive to source phase noise and polarization-state rotation in the fiber link, and uses simple electronic threshold detection. Coherent correlation and anticorrelation are demonstrated experimentally, and practical requirements are examined.

Experimental demonstration of coherent correlation (the upper plot, lower trace) and anticorrelation (the lower plot). In the upper plot, upper trace, the transmitted pulses are also shown. The expected patterns are 1 0 116 1 0 1 (correlation) and 2 0 2 0 2 0 2 (anticorrelation). The intensity scales are the same for the three traces.
