Abstract

A plasmonic “molecule” consisting of a radiative element coupled with a subradiant (dark) element is theoretically investigated. The plasmonic molecule shows electromagnetic response that closely resembles the electromagnetically induced transparency in an atomic system. Because of its subwavelength dimension, this electromagnetically induced transparency-like molecule can be used as a building block to construct a “slow light” plasmonic metamaterial.

Slowing light with plasmonic molecules

Published 18 August 2008

The response of nanostructured metal strips to an electromagnetic field may turn out to be similar to that of atomic gases. Periodic arrays of these artificial metal “molecules” could in principle form a metamaterial that slows light pulses and is easily integrated into optical circuits.
