Abstract

We developed superconducting nanowire single-photon detectors (SNSPDs) based on tungsten silicide (WSi), that show saturated internal detection efficiency from 2.1 to 5.5 mum wavelength.

Tungsten Germanide Superconducting Nanowire Single-Photon Detectors with Saturated Internal Detection Efficiency at Wavelengths up to 29 μm

Benedikt Hampel, Daniel Kuznesof, Andrew S. Mueller +13 more

Superconducting nanowire single-photon detectors (SNSPDs) are among the most sensitive single-photon detectors available and have the potential to transform fields ranging from infrared astrophysics to molecular spectroscopy. However, extending their performance into the mid-infrared spectral region - crucial for applications such as exoplanet transit spectroscopy and vibrational fingerprinting of molecules - has remained a major challenge, primarily due to material limitations and scalability constraints. Here, we report on the development of SNSPDs based on tungsten germanide, a novel material system that combines high mid-infrared sensitivity with compatibility for large-scale fabrication. Our detectors exhibit saturated internal detection efficiency at wavelengths up to 29 μm, while using 2.7x thicker films (8 nm vs 3 nm) and up to 4.5x wider nanowires (360 nm vs 80 nm) compared to mid-infrared-optimized SNSPDs fabricated from tungsten silicide. This advance will enable scalable, high-performance single-photon detection in a spectral region that was previously inaccessible, opening new frontiers in remote sensing, thermal imaging, environmental monitoring, molecular physics, and astronomy.

Superconducting nanowire single photon detectors and detector arrays in the mid-infrared

Varun Boehm Verma, Boris A. Korzh, Emma E. Wollman +8 more

We will discuss recently-developed approaches to improve sensitivity of superconducting nanowire single photon detectors in the mid-infrared, showing saturated internal detection efficiency up to a wavelength of 10 microns. We will also show preliminary data from small 64-element SNSPD arrays with high internal detection efficiency in the midinfrared at 3.5 μm, and will discuss calibration techniques we are developing for measuring system detection efficiency in this region of the spectrum.

Pushing The Limits of Mid-Wave Infrared Detection with Superconducting Nanowire Single-Photon Detectors

Eitan Oksenberg, Ronan Gourgues, Steffen Meder +4 more

Extending single-photon detection capabilities into the mid- infrared is expected to have far-reaching implications for long-wavelength quantum optics, quantum and free-space communication, astronomy, environmental monitoring, and fundamental molecular sciences. We showcase the development of short-wave infrared (2.2-2.3 µm) and mid- wave infrared (3.0 µm) superconducting nanowire single-photon detectors (SNSPDs). In both wavelength ranges, we venture beyond state-of-the-art and achieve the best-reported system detection efficiencies and specific detectivity. We discuss the challenges in cryogenics, optics, and SNSPD design and use our mid-infrared single-photon detection to characterize emerging materials platforms and quantum emitters in a previously unattainable manner.
