Tunable Plasmon Induced Transparency in Graphene and Hyperbolic Metamaterial-Based Structure

Abstract: A specially designed tunable hyperbolic metamaterial (HMM) based on plasmon induced transparency (PIT) of fractal in the near-infrared (NIR) regime was proposed. The HMM-layer constitutes the top metasurface, which is comprised of fractal-like nanospheres of silver (Ag) metal. A bilayer of graphene is sandwiched between the top HMM and bottom silicon (Si) substrate. The permittivity of graphene bilayer was deduced corresponding to different chemical potentials (of graphene). PIT of the proposed structure was o… Show more

“…Among a variety of photonic devices, plasmonic antennas are of great importance, having the ability to convert free space propagating electromagnetic radiation to highly localized energy, resulting in significant near-field enhancement [2]. Enhanced near-field empowers a wide verity of applications, such as spectroscopy, biosensing, light trapping, energy harvesting, and improved quantum emission [3]. Various modeling prerequisites, i.e., surface plasmon resonant wavelength, polarization, and spectral responses, should be considered in designing efficient plasmonic antennas.…”

“…These possess opposite signs for the parallel and perpendicular components of effective permittivity. Varieties of HMMs have been reported in the literature operating in the terahertz (THz) and optical regimes [4], [5] for potential applications in super resolution imaging [1], [6], filtering [7], [8], extreme polarization anisotropy of photoluminescence [9], energy harvesting [10], biosensors [11], [12], and absorbers [10], [13]- [15].…”
