    Nyckelord :LSCM; NIR; SNSPD; LSCM; NIR; SNSPD;

    Sammanfattning : In this thesis a near-infrared laser scanning confocal microscope (NIR-LSCM) is built to operate with optimal performance at 1550nm in combination with simultaneous LED light imaging at 970nm. For detection, a camera equipped with a complementary metal oxide semiconductor (CMOS) sensor and a superconducting nanowire single photon detector (SNSPD) are used for the LED part and the LSCM part, respectively.

  7. 5. Statistical Analysis of Dark Counts in Superconducting Nanowire Single Photon Detectors

    Kandidat-uppsats, KTH/Fysik

    Författare :Anton Cakste; Martin Andrae; [2022]
    Nyckelord :Single-Photon Detector; SNSPD; Dark Counts; Quantum Random Number Generator; Afterpulsing;

    Sammanfattning : In this paper we perform a statistical analysis of dark counts in superconducting nanowire single photon detectors (SNSPDs) with the end goal of creating a quantum random number generator (QRNG) using these dark counts. We confirm that dark counts are Poissonian for low bias currents and that no afterpulsing is present. LÄS MER
