Abstract: In this paper the operation of quantum dot lasers under optical feedback is studied on the basis of calculated Lyapunov exponents of the dynamic multi-population rate-equations. Influence of the direct capture path for the wetting layer carriers on the sensitivity to initial conditions is discussed. Results show that positive exponents are achieved for different current injection scenarios, and that negative exponents are mainly due to carriers in the dot confined states. Furthermore, existence of hiperchaos is obtained with both cascade and direct capture models.
