Abstract

Quantum dot-micropillar lasers provide a platform for investigating exciting physics at the crossroads between non-linear dynamics and nanophotonics. Due to their low mode volume and good resonator quality, they operate in the regime of cavity quantum electrodynamics, where single emitter effects and high spontaneous emission noise become prominent. Moreover, it is vital to understand the parameter space of such feedback-coupled microlasers when trying to address the fascinating applications of non-linear dynamics in delay coupled systems, such as zero-lag synchronization or reservoir computing [1]. So far the chaotic dynamics of feedback-coupled lasers have been mainly studied in the classical regime leaving open the question of the limits of feedback effects when operating a laser with few photons in the cavity.
