In this talk single-photon detectors based on superconducting nanowires will be described, which provide unmatched sensitivity, speed and temporal resolution at telecom wavelengths. After a general overview of the operation principle and performance, the physical processes governing the detector's single- and multi-photon response will be addressed. Novel detector concepts leading to more advanced functionalities, such as photon-number-resolution, will also be discussed.
Bio: Andrea Fiore graduated in Electrical Engineering (1994) and in Physics (1996) at the University of Rome "La Sapienza". From 1994 to 1997 he carried out his PhD thesis on nonlinear frequency conversion in semiconductor waveguides at Thomson CSF Central Research Laboratory (Orsay, France). He then held postdoctoral appointments at the University of California at Santa Barbara (1997-98) on vertical-cavity surface-emitting lasers and at the Ecole Polytechnique Fédérale de Lausanne (1998-2001) on quantum dot lasers, and a researcher position at the Italian National Research Council (2001-2002). From 2002 to 2007, he led the activity on Quantum Devices (quantum dot lasers, single-photon sources and detectors) at the Ecole Polytechnique Fédérale de Lausanne as assistant professor. Since October 2007, he has been full professor at TU/e. Prof. Fiore has been a principal investigator in many national projects (including the prestigious “Professeur boursier” and “Vici” personal grants), team leader in four EU projects, and coordinator of EU-FP6 project “SINPHONIA”. He has coauthored over 100 journal articles and given around 30 invited talks at international conferences.
