Classical and Quantum Plasmonics in Graphene Nanodisks: the Role of Edge States [PDF]

, 2014
Edge states are ubiquitous for many condensed matter systems with multicomponent wave functions. For example, edge states play a crucial role in transport in zigzag graphene nanoribbons.

Digital Plasmonic Holography [PDF]

Imaging and Applied Optics 2018 (3D, AO, AIO, COSI, DH, IS, LACSEA, LS&C, MATH, pcAOP), 2018
AbstractWe demonstrate digital plasmonic holography for direct in-plane imaging with propagating surface-plasmon waves. Imaging with surface plasmons suffers from the lack of simple in-plane lenses and mirrors. Lens-less digital holography techniques, however, rely on digitally decoding an interference pattern between a reference wave and an object ...

Benchmarking the Use of Heavily-Doped Ge Against Noble Metals for Plasmonics and Sensing in the Mid-Infrared [PDF]

, 2016
Despite the recent introduction of heavily-doped semiconductors for mid-infrared plasmonics, it still remains an open point whether such materials can compete with noble metals.

PLASMONIC LASERS [PDF]

, 2009
Surface plasmon polaritons (SPP)-based subwavelength metallic structures for laser amplification, emission, and collimation were introduced in this chapter. The plasmonic structures here act as a type of microlens which is integrated together with the laser for beam shaping or collimation.

Plasmon transport in graphene investigated by time-resolved measurement [PDF]

, 2012
Plasmons, which are collective charge oscillations, offer the potential to use optical signals in nano-scale electric circuits. Recently, plasmonics using graphene have attracted interest, particularly because of the tunable plasmon frequency through the

“Deterministic” Quantum Plasmonics [PDF]

Nano Letters, 2010
We demonstrate “deterministic” launching of propagative quantum surface-plasmon polaritons at freely chosen positions on gold plasmonic receptacles. This is achieved by using as a plasmon launcher a near-field scanning optical source made of a diamond nanocrystal with two nitrogen-vacancy color-center occupancy.

Transformation Optics for Plasmonics

, 2010
A new strategy to control the flow of surface plasmon polaritons at metallic surfaces is presented. It is based on the application of the concept of Transformation Optics to devise the optical parameters of the dielectric medium placed on top of the ...

Plasmonic aerosols

Physical Review B, 2019
Plasmonic nanoparticles resonantly couple to and confine light below the diffraction limit. This mechanism has enabled a modern renaissance in optical materials, with potential applications ranging from sensing and circuitry to renewable energies and medicines.

Spacer layer engineering for ultrasensitive Hg(II) detection on surface plasmon-coupled emission platform

Nanotechnology Reviews, 2017
In this work, we demonstrate for the first time the ultrasensitive detection of Hg2+ ions with femtomolar sensitivity in water samples with the use of the surface plasmon-coupled emission (SPCE) platform.
