Abstract

Semiconductor nanowires offer a powerful platform for engineering light at the nanoscale by controlling their size and shape in order to guide light efficiently and minimize undesired reflections. In this work we have shaped the nanowires with a unique tapering to realize bright quantum dot based entangled photon sources and high efficiency single photon detectors with high speed and timing resolution over an unprecedented bandwidth.
