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

      Gudjonson, Herman; Kats, Mikhail; Liu, Kun; Nie, Zhihong; Kumacheva, Eugenia; Capasso, Federico (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 

      Yu, Nanfang; Wang, Qi Jie; Kats, Mikhail A; Fan, Jonathan A.; Khanna, Suraj P.; Li, Lianhe; Davies, A. Giles; Linfield, Edmund H.; Capasso, Federico (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 

      Lipomi, Darren J.; Kats, Mikhail A; Kim, Philseok; Kang, Sung Hoon; Aizenberg, Joanna; Capasso, Federico; Whitesides, George McClelland (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 

      Genevet, Patrice; Dellinger, Jean; Blanchard, Romain; She, Alan Jenting; Petit, Marlene; Cluzel, Benoit; Kats, Mikhail A; de Fornel, Frederique; Capasso, Federico (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 

      Genevet, Patrice; Lin, Jiao; Kats, Mikhail A; Capasso, Federico (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 

      Genevet, Patrice; Tetienne, Jean-Philippe; Gatzogiannis, Evangelos; Blanchard, Romain; Kats, Mikhail A; Scully, Marlan O.; Capasso, Federico (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 

      Capasso, Federico; Yu, Nanfang; Kats, Mikhail A; Pflügl, Christian; Geiser, Markus; Wang, Qi Jie; Belkin, Mikhail A.; Fischer, Milan; Wittmann, Andreas; Faist, Jérôme; Edamura, Tadataka; Furuta, Shinichi; Yamanishi, Masamichi; Kan, Hirofumi (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 

      Kats, Mikhail A (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 

      Lipomi, Darren J.; Martinez, Ramses V.; Kats, Mikhail A; Kang, Sung H.; Kim, Philseok; Aizenberg, Joanna; Capasso, Federico; Whitesides, George McClelland (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 ...
