Abstract

We investigate the detrimental effect of chaotic noise on the performance of an optical chaos cryptosystem. Hyperchaos is generated in the emitter and receiver systems with Mach-Zehnder interferometers fed by semiconductor lasers and subjected to electro-optical feedback. In this optical chaos cryptosystem, (chaotic) noise originates from the mismatch in parameters between the emitter and the receiver. We therefore determine the amplitude of this noise as a fonction of the parameter mismatch, and we evaluate its effect on the bit error rate (BER) performance of the communication system. Analytical predictions are confirmed by numerical simulations and experimental results.
