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)
In this paper, we demonstrate the applicability of the OFDM multiple-access technique to optical chaos-based communications. We show that using an optoelectronic oscillator with multiple nonlinear delayed feedback loops, it is possible to transmit simultaneously multiple data streams with better spectral efficiency than a single stream.
We numerically study the synchronization of two unidirectionally coupled single-mode semiconductor lasers in a master-slave configuration. The master laser is an external-cavity laser that operates in a chaotic regime while for the slave laser we consider two configurations. In the first one, the slave laser is also an external-cavity laser, subjected to,(More)
