Real-Time Density Functional Tight Binding: A New Computational Tool for Probing Electronic Properties of Plasmonic Systems

Ilawe N.V., Wong B.M., University of California Riverside, US
Light-harvesting systems and plasmonic materials continue to garner significant attention due to their importance in both energy conversion and sensitive detection technologies. However, several challenges exist in improving their performance: these electronic multifunctional systems are [...]

Giant Enhancement of the Chiro-Optic Response of Chiral Plasmonic Media using Structured Light

Baev A., Furlani E.P., Haus J.W., Prasad P.N., Reddy I.V.A.K., Sukhotskiy V., University at Buffalo (SUNY), US
We propose an approach to achieve a great enhancement and broad spectral tunability of the chiro-optic response of plasmonic metasurfaces by exploiting their interaction with light of complex polarization, endowed with both spin (SAM) and [...]

Integrated Surface-Enhanced Raman Spectroscopy Sensors for Process Monitoring

Atanasoff G., Briber R.M., Metting C., Rabin O., von Bredow H., Zhang K., Zhang X., University of Maryland, US
Optical metamaterials obtain their unique properties from the combination of nanoscale plasmonic components and dielectric components. Reproducible mass-production of metamaterials is challenging but desirable for applications such as surface-enhanced Raman scattering (SERS) for chemical sensing. [...]

Self-Assembled Polystyrene Nanospheres for Plasmonic Enhancement in Biosensor Applications

Dawson J.M., Norville C., Smith K., Windham M., West Virginia University, US
The field of portable, point-of care biosensing has expanded in recent years to encompass a wide range of application areas, with detection of targets accomplished by a variety of techniques. Application-specific needs of further reduced [...]

Optical characterizations of multi-shape nanoparticles in polymer thin film layers

Ackermann J., Berginc G., Carlberg M., Escoubas L., Le Rouzo J., Margeat O., Pourcin F., Sauvage R.-M., Aix Marseille University, FR
Metallic nanoparticles are currently a hot topic thanks to their tuneable optical properties. Indeed, their light absorption or scattering is material, size and shape, but also environment dependent. We aim to take advantage of these [...]

Plasmonic structure integrated single-photon detectors for absorptance and polarization contrast maximization

Bánhelyi B., Csendes T., Csete M., Maráczi D., Szabó G., Szenes A., University of Szeged, HU
Superconducting nanowire single photon detectors (SNSPDs) are important for single-photon detection at 1550 nm infrared wavelength in quantum information processing (QIP), telecommunication and astronomy [1, 2]. Absorptance of single photons with a specific polarization has [...]

Light Trapping in Solar Cells Using Nanostructured Reflectors: A Responsivity-Based Model Applied to Waveguide Mode Matching

Shahriad T., Shepard S.R., Louisiana Tech University, US
Although theoretically predicted that periodic photonic nanostructures can outperform the pseudo random structures in light trapping in solar cells, still the disputation regarding this topic is at the top. To enlighten the world about the [...]

Plasmon enhanced silver quantum cluster fluorescence for biochemical applications

Bernard S., Kutter J.P., Mogensen K.B., Technical University of Denmark, DK
Silver quantum clusters (AgQCs) consisting of typically 4-10 atoms and known to be highly fluorescing in the visible wavelength range. Here, plasmon-enhanced silver quantum cluster fluorescence is employed for chemical sensing in a simple microfluidic [...]

Plasmon-enhanced Optical Rotation in Nanostructured Metasurfaces

Alali F., Furlani E.P., Kim Y.H., University at Buffalo (SUNY), US
Advancements in nanotechnology have enabled the realization of unique artificial materials for applications in the field of nanophotonics. Such metamaterials are engineered with sub-wavelength features to provide extraordinary optical properties such as negative refraction1, slow [...]

Silver Nanowires for Plasmon Induced Enhancement of Optical Absorption in Thin-Film Silicon Solar Cells

Mailhes R., Institut des Nanotechnologies de Lyon (INL), FR
Plasmonic effects for photovoltaics are investigated through this communication. We present here an innovative design with integrated silver nanocylinders located at the rear side of a thin crystalline silicon cell. Numerical simulations (FDTD) show that [...]
