Secure Communication Coupled Laser Based on Chaotic Rössler Circuits
Raied K. Jamal and Dina A. Kafi

We present synchronization between two bidirectional coupled laser Rössler circuits for satisfying secure communication. The two circuits are synchronized via one variable dynamic and the external signal is transmitted by another variable dynamic. This system exhibits more fixity and flexibility. Experimentally and numerically results are studied by changing the bidirectional coupling factor. The sinusoidal signal is used in secure communications.
