Abstract
This paper explores a quantum infrared detector operating in the ultra-strong light-matter coupling regime driven by collective electronic excitations. Experiments are corroborated by a microscopic quantum theory that solves fermionic transport with strong collective electronic effects. The findings open new avenues for optoelectronic devices based on coherent electron-photon interaction, optimizing quantum cascade detectors in strongly non-perturbative coupling with light.
