• #### Accounting for inhomogeneous broadening in nano-optics by electromagnetic modeling based on Monte Carlo methods ﻿

(Proceedings of the National Academy of Sciences, 2014)
Many experimental systems consist of large ensembles of uncoupled or weakly interacting elements operating as a single whole; this is particularly the case for applications in nano-optics and plasmonics, including colloidal ...
• #### Designer spoof surface plasmon structures collimate terahertz laser beams ﻿

(Nature Publishing Group, 2010)
Surface plasmons have found a broad range of applications in photonic devices at visible and near-infrared wavelengths. In contrast, longer-wavelength surface electromagnetic waves, known as Sommerfeld or Zenneck waves, ...
• #### Fabrication and Replication of Arrays of Single- or Multicomponent Nanostructures by Replica Molding and Mechanical Sectioning ﻿

(American Chemical Society (ACS), 2010)
This paper describes the fabrication of arrays of nanostructures (rings, crescents, counterfacing split rings, cylinders, coaxial cylinders, and other structures) by a four-step process: (i) molding an array of epoxy posts ...
• #### Generation of Two-Dimensional Plasmonic Bottle Beams ﻿

(Optical Society of America, 2013)
By analogy to the three dimensional optical bottle beam, we introduce the plasmonic bottle beam: a two dimensional surface wave which features a lattice of plasmonic bottles, i.e. alternating regions of bright focii ...
• #### Holographic Detection of the Orbital Angular Momentum of Light With Plasmonic Photodiodes ﻿

(Nature Publishing Group, 2012)
Metallic components such as plasmonic gratings and plasmonic lenses are routinely used to convert free-space beams into propagating surface plasmon polaritons and vice versa. This generation of couplers handles relatively ...
• #### Large Enhancement of Nonlinear Optical Phenomena by Plasmonic Nanocavity Gratings ﻿

(American Chemical Society (ACS), 2010)
Enhancing nonlinear processes at the nanoscale is a crucial step toward the development of nanophotonics and new spectroscopy techniques. Here we demonstrate a novel plasmonic structure, called plasmonic nanocavity grating, ...
• #### Multi-Beam Multi-Wavelength Semiconductor Lasers ﻿

(American Institute of Physics, 2009)
Multibeam emission and spatial wavelength demultiplexing in semiconductor lasers by patterning their facets with plasmonic structures is reported. Specifically, a single-wavelength laser was made to emit beams in two ...
• #### Optics at interfaces: ultra-thin color coatings, perfect absorbers, and metasurfaces ﻿

(2014-02-25)
The vast majority of optical components and devices in use today can be grouped under the umbrella of bulk optics''; i.e. they generally have a non-negligible thickness compared to the wavelength of light. This is true ...
• #### Patterning the Tips of Optical Fibers with Metallic Nanostructures Using Nanoskiving ﻿

(American Chemical Society (ACS), 2011)
Convenient and inexpensive methods to pattern the facets of optical fibers with metallic nanostructures would enable many applications. This communication reports a method to generate and transfer arrays of metallic ...
