Modeling the effect of superconductor properties on sensitivity and responsivity of superconducting nanowire single photon detector

S. Haldar, Arun Sehrawat, Krishna Balasubramanian

Superconducting nanowire single photon detector (SNSPD) is a leading candidate for applications requiring the fundamental limit of light detection at high detection rates. While SNSPD technology employing nanowires from conventional low temperature superconducting detectors is mature with several commercial solutions, other material options with higher transition temperature approaching liquid nitrogen with faster signal responses are actively being explored. In this context, we develop a comprehensive model that predicts the final potential response from an SNSPD incorporating several physical and material aspects. A phase diagram of photon detection is developed that describes the latching phases and the photon sensitivity as a function of biasing current and temperature for both low temperature and high temperature superconductors. On the one hand, while low temperature superconductors are observed to be more sensitive than high temperature superconductors (HTSs) under any given biasing condition, a biasing window for a single photon detection with HTS nanowires is identified. On the other hand, HTS nanowires demonstrate three orders of magnitude faster response times than the low temperature superconductor nanowire at the same biasing condition, making it uniquely suited for several practical applications.

Graphene-Based Josephson-Junction Single-Photon Detector

Detecting single photons is essential for numerous technologies, from quantum computing to observations of the faintest objects in the universe. The authors propose a detector based on graphene's dual abilities to absorb light across a huge range of wavelengths, and to experience an extreme rise in electronic temperature by absorbing just one photon. Simulations show that these properties allow for high detection efficiency, when the graphene is coupled to superconductors in a Josephson junction at cryogenic temperatures.

Two-dimensional cuprate nanodetector with single telecom photon sensitivity at T = 20 K

Abstract Detecting light at the single-photon level is one of the pillars of emergent photonic technologies. This is realized through state-of-the-art superconducting detectors that offer efficient, broadband and fast response. However, the use of low T C superconducting thin films limits their operation temperature to approximately 4 K and below. Here, we demonstrate proof-of-concept nanodetectors based on exfoliated, two-dimensional cuprate superconductor Bi2Sr2CaCu2O8-δ that exhibit single-photon sensitivity at telecom wavelength at a record temperature of T = 20 K. These non-optimized devices exhibit a slow ∼ m s reset time and a low detection efficiency ( ∼ 10 − 4 ). We realize the elusive prospect of single-photon sensitivity on a high-T C nanodetector thanks to a novel approach, combining van der Waals fabrication techniques and a non-invasive nanopatterning based on light ion irradiation. This result paves the way for broader application of single-photon technologies, relaxing the cryogenic constraints for single-photon detection at telecom wavelength.
