| Abstract: | We introduce a novel metal-embedded semiconductor pillar structure including quantum dots as highly efficient single-photon sources for quantum information applications. We have developed related processes for fabricating the proposed structure and have demonstrated strongly suppressed multi-photon generation and improved photon extraction efficiency. As a result, under non-resonant excitation, which is highly preferable for practical use, single-photon purity with g(2)(0) as low as 0.015 has been measured. The extremely small semiconductor volume of the metal embedded structure is a crucial factor for this observation. Moreover, single-photon generation from a single quantum dot at a rate of up to 6.4 million per second has been achieved. (© 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim) |
