Shahverdiev and K. A. Shore<br/>This paper provides a report of chaos synchronization regimes which may be accessed in both unidirectionally and bidirectionally coupled multiple-time-delay semiconductor lasers. We demonstrate that in bidirectionally coupled multiple-time-delay lasers additional feedback can considerably enhance sy...<br/>[Phys. Rev. E 77, 057201] Published Wed May 07, 2008 E. M.
