Suppression of Chaos Time Delay Signature in a Ring Network Consisting of Three Semiconductor Lasers Coupled With Heterogeneous Delays

The properties of chaos time delay signature (TDS) in a ring network consisting of three mutually coupled semiconductor lasers (MCSLs) are investigated numerically, where heterogeneous coupling delays are proposed to obtain the TDS concealment from the intensity chaos in wide parameter regions. The evolution of the TDS patterns, which are quantified via the autocorrelation function, for a ring network with identical coupling delays as well as...
