We numerically demonstrate multiplexing and demultiplexing of two distinct chaotic optical signals with strongly overlapped spectra, which are generated by mutually coupled external-cavity semiconductor lasers. Demultiplexing is performed by complete chaos synchronization, while the lasers at the receiving end are optically injected with the same(More)
We propose a general method for constructing multi-message chaos-based communications schemes based on the use of a single nonlinear oscillator subjected to multiple delayed feedbacks. Chaotic dynamics produced by nonlinear oscillators can be used to convey [1] or encrypt [2] information-bearing messages. In particular, optical chaos has proven to be a(More)
