摘要：

We calculate the integrated-pulse quantum efficiency of single-photon sources in the cavity quantum electrodynamics ( QED) strong-coupling regime. An analytical expression for the quantum efficiency is obtained in the Weisskopf-Wigner approximation. Optimal conditions for a high quantum efficiency and a temporally localized photon emission rate are examined. We show the condition under which the earlier result of Law and Kimble [ J. Mod. Opt. 44, 2067 ( 1997)] can be used as the first approximation to our result. (c) 2005 Optical Society of America.
