Abstract
We consider Josephson oscillations between two coupled, quasiresonantly pumped exciton-polariton (polariton) modes. We analyze the regions of stability and periodic oscillations of such a system and show that the spin degree of freedom allows a chaotic behavior. We show that two spatially separated polariton Josephson junctions can be synchronized and used for data encryption and transfer. Due to the strong nonlinearity of polariton-polariton interactions, chaos communication at rates up to 50 Gb/s is possible, which is at least ten times faster than the results obtained for other systems.
