A versatile setup for the measurement of temporal photon-correlations for sources with coherence times similar to detector dead-times — •Johannes Hölzl1,2, Alexandra Popp1, Thomas Mehringer1,2, Henning Weier3, and Joachim von Zanthier1,2 — 1Institut für Optik, Information und Photonik, Universität Erlangen-Nürnberg, 91058 Erlangen — 22 Erlangen Graduate School in Advanced Optical Technologies (SAOT), Universität Erlangen-Nürnberg, 91052 Erlangen — 3qutools GmbH, 81371 München
We present a Hanbury-Brown Twiss Setup to measure temporal photon-correlations of light sources with coherence times down to hundreds of picoseconds. Effects occuring due to the peculiarities of the single-photon-detectors like dead-time and afterpulsing and their influence on the results of the measurement are discussed.
