Paper Abstract

In recent years quantum dot lasers (QDLs) and optically injected QDLs in particular, have provided a new arena for the demonstration of many intriguing non-linear phenomena. We show here that slow optothermal relaxations may significantly affect the output dynamics in QDLs for both the free running and the external injection configurations. In particular, square-wave intensity drop-outs and pulsations can be obtained reminiscent of Fitzhugh-Nagumo excitable dynamics.
