Paper Abstract

We experimentally and numerically investigated the time delay (TD) signature suppression in a mutually delay-coupled semiconductor lasers (MDC-SL) system. The results show that excellent TD signature suppression can be achieved and all TD signatures are suppressed into background noise level. Meantime, two chaotic sequences are obtained concurrently and the corresponding self-correlation curves exhibit almost perfect δ function profile.
