Ultrawide thermal free-carrier tuning of dielectric antennas coupled to epsilon-near-zero substrates
Achieving large tunability of subwavelength resonators is a central challenge in nanophotonics. Here the authors demonstrate refractive index tuning at mid-infrared wavelengths using temperature-dependent control over the low loss plasma frequency in III-V semiconductors.
