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…
Cavity QED Control of Quantum Hall Stripes
Lorenzo Graziotto, Josefine Enkner, Sambuddha Chattopadhyay +7
Controlling quantum phases of materials with vacuum field fluctuations in engineered cavities is a novel route towards the optical control of emergent phenomena. We demonstrate, us…
Heterodyne coherent detection of the electric field temporal trace emitted by frequency-modulated comb lasers
Baptiste Chomet, Salim Basceken, Djamal Gacemi +6
Frequency-modulated (FM) combs are produced by mode-locked lasers in which the electric field has a linearly chirped frequency and nearly constant amplitude. This regime of operati…
Microring quantum cascade surface emitting lasers
David Stark, Mattias Beck, Jérôme Faist
We miniaturize a vertically-coupled in-plane whispering gallery mode cavity incorporating a quantum cascade gain medium, aiming to realize the mid-infrared counterpart to the verti…
