Abstract
We discuss the efficiency of single photon sources based on a single quasi-monochromatic emitter (such as a semiconductor quantum dot) inserted in a pillar microcavity. We show that their efficiency, which is in principle excellent thanks to the Purcell effect, can be drastically limited by extrinsic cavity losses, such as those related to the scattering by the sidewalls roughness. We present novel design rules for micropillars in view of this application and show that for the well-mastered GaAs/AlAs system more than 70% of the emission can be concentrated into the collimated emission beam associated with the fundamental cavity mode.
