Title: Measuring intensity correlations with a two-element superconducting nanowire single-photon detector
Published: November 24, 2008
Abstract: Second-order intensity correlation measurements were made using a two-element superconducting nanowire single photon detector (SNSPD) without the need for an optical beam splitter. This approach can be used to obtain a 50-ps full width at half maximum timing resolution over a wide range of visible and near-infrared wavelengths and can be extended to measure higher-order intensity correlations. Measurements of the second-order intensity correlation of a pulsed laser and an InGaAs quantum dot were made using both a two-element SNSPD and a conventional Hanbury Brown-Twiss interferometer to demonstrate the accuracy and advantages of the multielement SNSPD.
