Paper Abstract

In the last few years considerable effort has been devoted to the miniaturization of quantum information technology on semiconductor chips; in addition, recent developments in quantum information theory have roused a growing interest in 'generalized' states of frequency correlation. Parametric generation in semiconductor waveguides allows roomtemperature operation in the telecom range. We propose and compare some microcavity-based schemes for the generation of counterpropagating photon pairs and we experimentally demonstrate a bright source emitting 1.2 × 10-11pairs/pump photon for a 1.8 mm long waveguide. The indistiguishability of the photons of the pair is measured via a Hong-Ou-Mandel two-photon interference experiment showing a visibility of 85 %. The versatility of the source to control the generated two-photon state is also discussed.
