摘要：
Time-delay (TD) signature performances of polarization-resolved chaos outputs from two mutually coupled vertical-cavity surface-emitting lasers (MC VCSELs) are investigated through detailed simulations by means of self-correlation function (SF) and permutation entropy (PE). The results show that, under suitable coupling strength (eta) and frequency detuning (Delta f) between the two MC VCSELs, the TD signatures of two polarization modes from each VCSEL can be suppressed simultaneously. Furthermore, based on the map of TD signature evolution in the parameter space of Delta f and eta, the optimal parameter region of TD signature suppression has been determined.
