Ultrafast (≈10 GHz) mid-IR modulator based on ultrafast electrical switching of the light–matter coupling

Mario Malerba, Stefano Pirotta, Guy Aubin, L Lucia, M Jeannin, J-M Manceau, A Bousseksou, Q Lin, J-F Lampin, E Peytavit, S Barbieri, L H Li, A G Davies, E H Linfield, Raffaele Colombelli

We demonstrate a free-space amplitude modulator for mid-infrared radiation (λ ≈ 9.6 μm) that operates at room temperature up to at least 20 GHz (above the −3 dB cutoff frequency measured at 8.2 GHz). The device relies on the ultrafast transition between weak- and strong-coupling regimes induced by…
