Detection of photon-level signals embedded in sunlight with an atomic photodetector
Laura Zarraoa, Tomas Lamich, Sondos Elsehimy +2
The detection of few-photon signals in a broadband background is an extreme challenge for photon counting, requiring filtering that accepts a narrow range of optical frequencies wh…

Cavity-enhanced detection of spin polarization in a microfabricated atomic vapor cell
MarÃa Hernández Ruiz, Yintao Ma, Hana Medhat +3
We demonstrate continuous Pound-Drever-Hall (PDH) nondestructive monitoring of the electron spin polarization of an atomic vapor in a microfabricated vapor cell within an optical r…
