Plasmon-Polaron Coupling in Conjugated Polymer on Infrared Nanoantennas.

Nano letters

Wang Z, Zhao J, Frank B, Ran Q, Adamo G, Giessen H, Soci C.
PMID: 26168373
Nano Lett. 2015 Aug 12;15(8):5382-7. doi: 10.1021/acs.nanolett.5b01760. Epub 2015 Jul 21.

We propose and demonstrate a novel type of coupling between polarons in a conjugated polymer and localized surface plasmons in infrared (IR) nanoantennas. The near-field interaction between plasmons and polarons is revealed by polarized photoinduced absorption measurements, probing mid-IR...

Dynamic granularity of imaging systems.

The Review of scientific instruments

Geissel M, Smith IC, Shores JE, Porter JL.
PMID: 26628138
Rev Sci Instrum. 2015 Nov;86(11):113701. doi: 10.1063/1.4934543.

Imaging systems that include a specific source, imaging concept, geometry, and detector have unique properties such as signal-to-noise ratio, dynamic range, spatial resolution, distortions, and contrast. Some of these properties are inherently connected, particularly dynamic range and spatial resolution....

Opt Express. 2017 Aug 21;25(17):19672-19679. doi: 10.1364/OE.25.019672.

We demonstrate orbital-angular momentum (OAM) light up to a topological charge of l=3 behind a single mode fiber. Femtosecond 3D direct laser writing is used to fabricate spiral phase plates of l=1,2 and 3, composed of 10 discrete steps,...

Hole-mask colloidal nanolithography combined with tilted-angle-rotation evaporation: A versatile method for fabrication of low-cost and large-area complex plasmonic nanostructures and metamaterials.

Beilstein journal of nanotechnology

Beilstein J Nanotechnol. 2014 May 06;5:577-86. doi: 10.3762/bjnano.5.68. eCollection 2014.

Many nano-optical applications require a suitable nanofabrication technology. Hole-mask colloidal nanolithography has proven to be a low-cost and large-area alternative for the fabrication of complex plasmonic nanostructures as well as metamaterials. In this paper, we describe the fabrication process...

Previously unknown isotopes (30)Ar and (29)Cl have been identified by measurement of the trajectories of their in-flight decay products (28)S+p+p and (28)S+p, respectively. The analysis of angular correlations of the fragments provided information on decay energies and the structure...

We present an analytic derivation for the enhancement of local optical chirality in the near field of plasmonic nanostructures by tuning the far-field polarization of external light. We illustrate the results by means of simulations with an achiral and...

Sub-micrometre accurate free-form optics by three-dimensional printing on single-mode fibres.
