Abstract | Этап №1 (дата окончания: 30.09.2009) Разработана методика изготовления сверхпроводниковых однофотонных детекторов (SSPD) с монокристаллической структурой пленки сверхмалой толщины. Изготовлены экспериментальные образцы сверхпроводниковых однофотонных детекторов (SSPD). Разработана методика пакетирования сверхпроводникового однофотонного детектора в оптический узел с одномодовым оптоволокном. Изготовлены экспериментальные образцы приемных модулей на основе однофотонных сверхпроводниковых детекторов из NbN-нанопленок. Этап №2 (дата окончания: 28.10.2009) Разработаны методы диагностики КМОП микросхем, гетероструктур и лазеров на квантовых точках и методика измерения мощности излучения полупроводниковых лазеров на квантовых точках с использованием сверхпроводниковых однофотонных детекторов (SSPD). Проведена технико-экономическая оценка рыночного потенциала полученных результатов. |

Title | High speed infrared photon counting with photon number resolving superconducting single-photon detectors (SSPDs) | Type | Conference Article | ||

Keywords | SSPD, SNSPD | ||||
Abstract | A review of development and characterization of the nanostructures consisting of several meander sections, all connected in parallel was presented. Such geometry leads to a significant decrease of the kinetic inductance, without a decrease of the SSPD active area. A new type of SSPDs possess the QE of large-active- area devices, but, simultaneously, allows achieving short response times and the GHz-counting rate. This new generation of superconducting detectors has another significant advantage for quantum key distribution, they have a photon number resolving capability and can distinguish more photons. | ||||

Keywords | NbN SSPD, SNSPD | ||||
Abstract | We present a new, simple to manufacture, single-photon detector (SPD), which can work from ultraviolet to near-infrared wavelengths of optical radiation and combines high speed of operation, high quantum efficiency (QE), and very low dark counts. The devices are superconducting and operate at temperature below 5 K. The physics of operation of our SPD is based on formation of a photon-induced resistive hotspot and subsequent appearance of a transient resistive barrier across an ultrathin and submicron-wide superconductor. | ||||

Title | Ultimate sensitivity of superconducting single-photon detectors in the visible to infrared range | Type | Miscellaneous | ||

Abstract | We present our quantum efficiency (QE) and noise equivalent power (NEP) measurements of the meandertype ultrathin NbN superconducting single-photon detector in the visible to infrared radiation range. The nanostructured devices with 3.5-nm film thickness demonstrate QE up to~ 10% at 1.3–1.55 µm wavelength, and up to 20% in the entire visible range. The detectors are sensitive to infrared radiation with the wavelengths down to~ 10 µm. NEP of about 2× 10-18 W/Hz1/2 was obtained at 1.3 µm wavelength. Such high sensitivity together with GHz-range counting speed, make NbN photon counters very promising for efficient, ultrafast quantum communications and another applications. We discuss the origin of dark counts in our devices and their ultimate sensitivity in terms of the resistive fluctuations in our superconducting nanostructured devices. | ||||
