Optical Slow-Wave Metamaterials and Their Tunability/Applications
Abstract
A classical effect of electromagnetically induced transparency (EIT) is demonstrated in a planar metamaterials in the ultraviolet regime. The EIT unit cell consists of a vertical cut wire as the bright resonator and two horizontal cut wire pairs as the dark element. The destructive interference between the two resonance paths leads to an EIT-like transmission spectrum of the metamaterial. This metamaterial design that enables excitation and tuning of the classical EIT effect would eventually lead to the development of electromagnetic slow light devices. And this planar EIT structure can be easily fabricated and integrated as ultra-compact sensor with high sensitivity.
