Hybrid Ferromagnet-SNSPDs: Single photon induced order-to-disorder transition in ferromagnets coupled to thin film superconductors
Leif Bauer, Daien He, Sathwik Bharadwaj +1
The development of midwave and longwave infrared single photon detectors is crucial for their emerging applications in spectroscopy, remote sensing, exoplanet detection, and free s…
Ultra-broadband Mid to Long-wave Infrared Spintronic Poisson Bolometer
Mohamed A. Mousa, Leif Bauer, Daien He +7
Infrared detectors have traditionally been divided into two fundamental classes, mid-wave (MWIR, 3-5 um) and long-wave (LWIR, 8-14 um). Integrating MWIR and LWIR within a single de…
Optical Response in Spintronic Poisson Bolometers
Ziyi Yang, Sakshi Gupta, Jehan Shalabi +5
Analog bolometers based on temperature-dependent phase-transition materials such as vanadium oxide (VOx) and barium titanate (BTO) represent the state of the art in uncooled infrar…
Enhanced Sensitivity to Blackbody Radiation in Spintronic Poisson Bolometers
Ziyi Yang, Sakshi Gupta, Jehan Shalabi +5
High-sensitivity long-wave infrared (LWIR) detection is crucial for observing weak thermal radiation. Recently, the Poisson bolometer has been proposed as a fundamentally new platf…
Long wave infrared detection using probabilistic spintronic bolometer arrays
Utkarsh Singh, Leif Bauer, Angshuman Deka +5
The use of probabilistic spintronic devices for infrared radiation detection has introduced a shift in approach to thermal imaging. The integration of probabilistic magnetic tunnel…
Unified Theory of Dark Count Rate and System Detection Efficiency for NbN, WSi Based Superconducting Single Photon Detectors
Daien He, Leif Bauer, Sathwik Bharadwaj +1
Predicting the behavior of superconducting nanowire single photon detectors (SNSPDs) is important as their use becomes more widespread in fields ranging from quantum computing to q…
Type-1.5 SNSPD: Interacting vortex theory of two bandgap superconducting single photon detectors
Leif Bauer, Daien He, Sathwik Bharadwaj +3
Photon detectors based on type-2 superconductors have found widespread applications from on-chip quantum computing to quantum remote sensing. Here, we develop the theory for a new…
