Dynamics of semiconductor lasers with external multicavities.
Extending a semiconductor laser by means of an external resonator providing a weak optical feedback causes high-dimensional chaotic fluctuations of the light intensity. Adding a second resonator with different round-trip time may turn these fluctuations into more ordered oscillations or even lead back to a stable steady-state operation. The stability range of periodic or continuous wave solutions can be increased by adding a third resonator to the system. This stabilizing effect of multicavities is shown experimentally and theoretically using numerical simulations based on an extended Lang-Kobayashi model and corresponding linear stability analysis of continuous wave solutions.
