    "abstract": "We discuss the efficiency of single photon sources based on a single\nquasi-monochromatic emitter (such as a semiconductor quantum dot) inserted in a\npillar microcavity. We show that their efficiency, which is in principle\nexcellent thanks to the Purcell effect, can be drastically limited by extrinsic\ncavity losses, such as those related to the scattering by the sidewalls\nroughness. We present novel design rules for micropillars in view of this\napplication and show that for the well-mastered GaAs/AlAs system more than 70%\nof the emission can be concentrated into the collimated emission beam\nassociated with the fundamental cavity mode.",
