ZHirose, S.Usuki, T.42.50.Ar71.35.-y78.55.Cr78.67.Hc549.8Regulated 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.WILEY-VCH Verlag GmbH & CoJournal Articleapplication/pdfhttp://hdl.handle.net/2115/5601https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/5601/1/PSS2-11.pdf1610-1634physica status solidi (c)211383338372005-11-08enginfo:doi/10.1002/pssc.200562027Copyright © 2005 John Wiley & Sons, Inc., physica status solidi (c), 2, 11,p3833-3837author
