Nanoscale Plasmonic Devices Based on Metal-Dielectric-Metal Stub Resonators

Abstract EN

We review some of the recent research activities on plasmonic devices based on metal-dielectric-metal (MDM) stub resonators for manipulating light at the nanoscale.

We first introduce slow-light subwavelength plasmonic waveguides based on plasmonic analogues of periodically loaded transmission lines and electromagnetically induced transparency.

In both cases, the structures consist of a MDM waveguide side-coupled to periodic arrays of MDM stub resonators.

We then introduce absorption switches consisting of a MDM plasmonic waveguide side-coupled to a MDM stub resonator filled with an active material.
