Abstract

Fabrication of plasmonic metamaterials having electromagnetically induced transparency (EIT)-like characteristics with sharp and strong spectral responses is a challenging task for device applications at near-infrared wavelengths. EIT-like effects in silver metamaterials consisting of dipole resonators and quadrupole resonators were experimentally demonstrated, and their characteristics were evaluated. Optical characteristics of the metamaterials could be controlled by the gap distance between the two resonators. At wavelengths around 820 nm, EIT-like effects with transmittance between 72% and 28% were observed for the metamaterials with gap distances between 13 and 69 nm. At a gap of 13 nm, a maximum modulation depth of 2.29 was achieved.
