Abstract

We experimentally demonstrate a strong-coupling-induced resonance splitting in indium-tin-oxide (ITO) based epsilon-near-zero (ENZ) metasurface with cross-shaped nanoantennas. An ∼11-nm blue shift of the carrier wavelength is observed for this metasurface under ∼4-GW/cm peak-power density.
