Bidirectional communication with time-delay concealment in a system combining all-optical intensity and electrooptical phase chaos

In this paper, we propose and study theoretically a novel architecture, which combines all-optical intensity chaos and electrooptical-phase chaos generator, allows for bidirectional secure communication. The configuration includes three all-optical chaotic semiconductor lasers and two identical phase-chaos electrooptic delayed oscillators in the optic-fiber link. We investigate the complexity degree of this chaotic time trace generated in this...
