Regulated single‐photon generation from an InAlAs quantum dot was demonstrated at a wavelength in which Si‐avalanche photodiode single‐photon detector has high quantum efficiency. Measured excitation power dependence of photon coincidence counts revealed that highly pure single‐photon emission was realized at low excitation powers. Beyond a critical excitation, population of multi‐exciton states in the quantum dot degraded the purity of single‐photon emission. (© 2005 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
