M.; Prieto-González, Iván CSIC ORCID; Granados, Daniel CSIC ORCID; González Taboada, Alfonso CSIC; García Martínez, Jorge Manuel CSIC ORCID CVN ; Postigo, Pablo Aitor CSIC ORCID | Fecha de publicación: | 2010 | Editor: | Optical Society of America | Citación: | Journal of the Optical Society of America - B - Optical Physics 27(6): A21-A24 (2010) | Resumen: | Photon correlation measurements on single InAs/GaAs quantum rings embedded in a photonic crystal lattice demonstrate single-photon emission with g(2)(0) values of 0.4 and photon antibunching between the exciton and biexciton emissions. The measured photon antibunching times of the excitons are longer than that of the biexcitons, resulting in the time asymmetry of the exciton-biexciton photon cross-correlation. Phonon sidebands due to the piezoelectric coupling of excitons to acoustic phonons broaden the emission lines and shift them to lower energies at low excitation intensity. | Descripción: | 4 páginas.-- OCIS Codes: (030.5290) Coherence and statistical optics : Photon statistics; (160.6000) Materials : Semiconductor materials; (160.5298) Materials : Photonic crystals | Versión del editor: | http://dx.doi.org/10.1364/JOSAB.27.000A21 | URI: | http://hdl.handle.net/10261/31962 | DOI: | 10.1364/JOSAB.27.000A21 | ISSN: | 0740-3224 |
