Query: Direct polariton-to-electron tunneling in quantum cascade detectors
  operating in the strong light-matter coupling regime   We demonstrate mid-infrared quantum cascade detectors (QCD) operating in the
strong light-matter coupling regime. They operate around $\lambda = 10~\mu m$
with a minimum Rabi splitting of 9.3 meV. A simple model based on the usual
description of transport in QCDs does not reproduce the polaritonic features in
the photo-current spectra. On the contrary, a more refined approach, based on
the semi-classical coupled modes theory, is capable to reproduce both optical
and electrical spectra with excellent agreement. By correlating
absorption/photo-response with the simulations, we demonstrate that - in this
system - resonant tunneling from the polaritonic states is the main extraction
mechanism. The dark intersubband states are not involved in the process,
contrary to what happens in electrically injected polaritonic emitters.
