Abstract

We propose a method to obtain intensity chaos of high dimensionality from a laser diode with a nonlinear delayed feedback. The core of the chaotic transmitter and receiver is formed by an electro-topic LiNbO3 modulator that is used to generate strong nonlinearities and chaotic waveforms. The method can be used for encrypting and decrypting a signal in a chaos-based communication system.
