Multi-mode Deep Strong Coupling in a Multi Quantum Well Fabry-Perot Cavity
Lucy Hale, Johan Andberger, Ethan Koskas +4
We present multi-mode deep-strong coupling in a multi-quantum well (N=166) heterostructure. The heterostructure itself acts as a Fabry-Perot cavity, for which the even cavity modes…

Terahertz chiral sub-wavelength cavities breaking time-reversal symmetry via ultra-strong light-matter interaction
Johan Andberger, Lorenzo Graziotto, Luca Sacchi +3
We demonstrate terahertz chiral sub-wavelength cavities that break time-reversal symmetry by coupling the degenerate linearly polarized modes of two orthogonal sets of nano-antenna…
