Photovoltaic Probe of Cavity Polaritons in a Quantum Cascade Structure
Luca Sapienza, Raffaele Colombelli, Angela Vasanelli +4
The strong coupling between an intersubband excitation in a quantum cascade structure and a photonic mode of a planar microcavity has been detected by angle-resolved photovoltaic m…
