TL;DR: The design, realization and characterization of strong coupling between an intersubband transition and a monolithic metamaterial nanocavity in the mid-infrared spectral range is presented and the conductive ground plane is implemented using a highly doped n+ layer.

TL;DR: In this article, the authors demonstrate strong polaritonic coupling between Mie photonic modes and intersubband transitions in semiconductor heterostructures, along with demonstrating ISB polaritons with Rabi splitting as large as 10%.

TL;DR: This work fabricates a complementary metasurface strongly coupled to an epsilon-near-zero (ENZ) mode operating in the long-wave region of the infrared spectrum and shows numerically the expected tunable spectral behavior of such coupled system under reverse and forward bias, which could be used in future electrically tunable detectors.

TL;DR: In this paper, a voltage-tunable plasmonic metasurface-based optical modulator is proposed to control the light-matter interaction with an external stimulus.

TL;DR: Experimental observation of viscoelastic nonlocalities in the infrared optical response of epsilon-near-zero nanofilms made of low-loss doped cadmium-oxide and evidence of the existence of nonlocal damping, i.e., viscosity, in the motion of optically-excited conduction electrons using a combination of spectroscopic ellipsometry data and predictions based on the vis coelastic hydrodynamic model.
