TLDR
Hybrid plasmonic waveguides as discussed by the authors employ a high-gain semiconductor nanostructure functioning as a gain medium that is separated from a metal substrate surface by a nanoscale thickness thick low-index gap.
Abstract
Hybrid plasmonic waveguides are described that employ a high-gain semiconductor nanostructure functioning as a gain medium that is separated from a metal substrate surface by a nanoscale thickness thick low-index gap. The waveguides are capable of efficient generation of sub-wavelength high intensity light and have the potential for large modulation bandwidth >1 THz.

Ultrashort broadband polarization beam splitter based on a combined hybrid plasmonic waveguide.

TL;DR: This design considerably reduces the length of the PBS to the submicron scale (920 nm, the shortest PBS reported to date) while offering polarization extinction ratios (PERs) and insertion losses (ILs) of ~0.6 dB, realizing a densely photonic integrated circuit.

Optical and Dynamical Properties of Chemically Synthesized Gold Nanoplates

TL;DR: In this paper, the optical properties of single crystal, micrometer-sized nanoplates were studied by scattered light and transient absorption experiments, and it was shown that the direction of propagation of the plasmon polariton (SPP) modes can be controlled through the polarization of the laser beam.

Directional spontaneous emission enhancement in hyperbolic metamaterials

TL;DR: In this paper, the authors experimentally demonstrate the control of spontaneous emission enhancement in multilayered Au/Al2O3 hyperbolic metamaterials (HMMs) using effective medium theory, and then the results are validated by experiments performed through variable angle spectroscopic ellipsometry.

Enhanced near band edge luminescence of Ti/ZnO nanorod heterostructures due to the surface diffusion of Ti.

TL;DR: The photoluminescence (PL) spectra show that the near band edge luminescence of ZnO in the ultraviolet (UV) region is enhanced as the thickness of Ti increases up to 5 nm and, thereafter, it falls.

Numerical Study of Gain-Assisted Terahertz Hybrid Plasmonic Waveguide

TL;DR: In this article, a numerical transfer matrix method was applied to investigate hybrid surface plasmon polaritons (HySPPs) waveguide structure, which consists of a high permittivity dielectric fiber separated from a metal surface with a low permittivities dielectrics gap.

Single-nanowire electrically driven lasers

TL;DR: In this paper, the authors investigate the feasibility of achieving electrically driven lasing from individual nanowires and show that these structures can function as Fabry-Perot optical cavities with mode spacing inversely related to the nanowire length.
