Design of Microlens Arrays for Thermal Imaging with Spintronic Poisson Bolometers
Ziyi Yang, Leif Bauer, Zubin Jacob
Infrared (IR) detectors are widely used due to their ability to sense thermal radiation. Recently, a room-temperature infrared detector known as the spintronic Poisson bolometer wa…
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…
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…
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…
Uncooled Poisson Bolometer for High-Speed Event-Based Long-wave Thermal Imaging
Mohamed A. Mousa, Leif Bauer, Utkarsh Singh +3
Event-based vision provides high-speed, energy-efficient sensing for applications such as autonomous navigation and motion tracking. However, implementing this technology in the lo…
Physics-Integrated Inference for Signal Recovery in Non-Gaussian Regimes
Mohamed A. Mousa, Leif Bauer, Ziyi Yang +3
High-performance room-temperature sensing is often limited by non-stationary fluctuations and non-Gaussian stochasticity. In spintronic devices, thermally activated Néel swi…
