Abstract

In this note we present some results concerning photon blockade and antibunching in a system consisting of a quantum dot embedded in a microcavity. We give analytic conditions for resonant and non-resonant photon blockade, valid for small values of the external pump amplitude. Starting from these results, we discuss the quantum states characteristics of the system within a master equation formalism and highlight quantities like stationary second order correlations both static and dynamic and one-photon purity.
