Physikalisches Institut, Universita¨t Heidelberg, Philosophenweg 12, 69120 Heidelberg, Germany(Dated: March 23, 2009)We demonstrate a robust fiber optics based fluorescence detec tor, fully integrated on an atom chip, whichdetects single atoms propagating in a guide with 66% efficien cy. We characterize the detector performance andthe atom flux by analysing the photon statistics. Near-perfect photon antibunching proves that single atoms aredetected, and allows us to study the second-order intensitycorrelation function of the fluorescence over threeorders of magnitude in atomic density.
