Dynamics of mutually coupled semiconductor lasers

Abstract

We present the results of a numerical study of the dynamical behavior of two mutually coupled semiconductor lasers.To do so a four- equations model is adopted together with injection current pulse shaping of each laser alone together with sinusoidal modulation of the injection current of each laser.The obtained results revealed varieties of dynamics in all the studied cases, which suggest the possibility of safe communication through beating of both lasers signals.
