Abstract

Performance of quantum dot lasers subject to optical feedback is numerically studied in this work from Lang-Ko - bayashi and multi-population rate-equation models. The approach adopted to study the characteristics of the laser response is based on the calculation of the Lyapunov exponents of the system and revealed the existence of chaos in shorter devices. Influence of the time-delay of the reflected back electrical field has also been addressed.
