CNR-IFN, Single-Photon Detection with Integrated Superconducting Nanowires

Printer-friendly versionSend by emailPDF version
Research Type: 

The Institute for Photonics and Nanotechnologies (IFN) is part of the Italian National Research Council (CNR), which is the largest public research institution in Italy.  Research at the Rome unit is focused on the development of superconducting nanowire single photon detectors (SNSPDs) integrated with advanced optical cavities and passive quantum-optics circuits on semiconducting materials. IFN-CNR exploits a 200 m2 clean room facility, equipped with a 100 kV Electron Beam Lithography system together with all the tools needed for micro and nanofabrication.
