Duplex chaotic message tranmission using polarization mode carriers in small networks of three chaotic vertical-cavity surface-emitting lasers

Duplex chaotic message transmission based on polarization mode carriers is investigated numerically in a small network consisting of three chaotic vertical-cavity surface-emitting lasers. The results show that, under proper conditions, two messages at the speed of a few GHz can be encoded/decoded separately and successfully. The performance of the communication is evaluated by using the well-known eye diagram and Q-factor.
