Chaos modulation for message encoding and decoding is investigated using two chaotic optical communication systems. With a message injected into the chaotic dynamics of the transmitter in chaos modulation, the complexity of the chaos is found to increase. Meanwhile, the synchronization quality is not influenced by the message encoding. The effect of channel noise is investigated and the bit error rate is calculated as a function of the signal-to-noise ratio for both systems.
