Phys. Rev. A 78, 013640 (2008) [11 pages]Single-atom detection with optical cavitiesReceived 23 May 2008; published 31 July 2008 We present a thorough analysis of single-atom detection using optical cavities. The large set of parameters that influence the signal-to-noise ratio for cavity detection is considered, with an emphasis on detunings, probe power, cavity finesse, and photon detection schemes. Real device operating restrictions for single photon counting modules and standard photodiodes are included in our discussion, with heterodyne detection emerging as the clearly favorable technique, particularly for detuned detection at high power. © 2008 The American Physical Society URL:
