TLDR
In this paper, the optical properties of metal-dielectric-metal structures with patterned top metallic surfaces, in the THz frequency range, were studied and a detailed analysis of the physical mechanisms which give rise to these photonic modes were provided.Abstract:
We present an experimental and theoretical study of the optical properties of metal-dielectric-metal structures with patterned top metallic surfaces, in the THz frequency range. When the thickness of the dielectric slab is very small with respect to the wavelength, these structures are able to support strongly localized electromagnetic modes, concentrated in the subwavelength metal-metal regions. We provide a detailed analysis of the physical mechanisms which give rise to these photonic modes. Furthermore, our model quantitatively predicts the resonance positions and their coupling to free space photons. We demonstrate that these structures provide an efficient and controllable way to convert the energy of far field propagating waves into near field energy.read more

TL;DR: The photonic architecture overcomes intrinsic limitations of the material, such as the drop of the electronic drift velocity with temperature, which constrains conventional geometries at cryogenic operation, and could benefit technologies such as high-speed multichannel coherent data transfer and high-precision molecular spectroscopy.

TL;DR: In this article, a highly doped semiconductor layer was inserted in a subwavelength plasmonic resonator to achieve a photonic gap of 38 meV, which is the highest ever reported for a light-matter coupled system at room temperature.

Surface plasmon subwavelength optics
TL;DR: By altering the structure of a metal's surface, the properties of surface plasmons—in particular their interaction with light—can be tailored, which could lead to miniaturized photonic circuits with length scales that are much smaller than those currently achieved.
