“…The maximum transmission bit rate is mainly limited by the relaxation oscillation frequency, which is typically in the GHz range. Besides the optical feedback schemes, optoelectronic feedback schemes have also turned out to be attractive systems for chaos communication (Goedgebuer, Larger, and Porte, 1998;Abarbanel et al, 2001;Liu, Chen, and Tang, 2002), achieving bit rates up to 10 Gb=s (Lavrov, Jacquot, and Larger, 2010).…”
