Winter College 2012 to focus on nano-optics, plasmonics

The annual event is 6-17 February.

The 2012 Winter College on Optics at the Abdus Salam International Centre for Theoretical Physics (ICTP) in Trieste, Italy, will focus on advances in nano-optics and plasmonics in February.

This year's event (6-17 February) is directed by SPIE Fellow Zohra Ben Lakhdar of Université de Tunis El Manar (Tunisia); Nikolay Zheludev of University of Southampton (UK); and Mario Bertolotti of the Università degli Studi di Roma La Sapienza (Italy). Local organizers are Joseph Niemela and Miltcho B. Danailov.

SPIE supports optics education at the Winter College on Optics, along with the International Commission for Optics, European Optical Society, Società Italiana di Ottica e Fotonica, U.S. National Academy of Science, IEEE Photonics Society, OSA, and the International Society on Optics Within Life Sciences.

More than 100 students and optics experts from around the world are expected to attend and share the latest research in optical science. A preliminary list of instructors at the 2012 Winter College on Optics includes:

  • Javier Aizpurua (Spain)
  • Fabio Antonio Bovino (Italy)
  • Marco Centini (Italy)
  • Sergey Gaponenko (Belarus)
  • Harald Giessen (Germany)
  • Oscar Eduardo Martinez (Argentina)
  • Francesco Michelotti (Italy)
  • Ekmel Ozbay (Turkey)
  • Concita Sibilia (Italy)
  • Mark Stockman (USA)
  • Anatoly Zayats (UK)

Winter College on Optics instructors will present new advances in nano-optics and nanophotonics with emphasis on plasmon physics and plasmonic devices. Lectures and demonstrations will cover an introduction to nanophotonics as well as nonlinear optics at the nanoscale, basic plasmon physics, and the increasing number of applications in imaging, biosensors, nanoantennas, communications, energy, displays, and light sources.

Surface plasmon polaritons (SPPs) are electromagnetic excitations on the surface of a good metal whose electromagnetic field is confined to the vicinity of the dielectric-metal interface. This confinement leads to an enhancement of the electromagnetic field at the interface, and the resulting increase in sensitivity is extensively used in chemo- and bio-sensors. The field enhancement is also responsible for surface enhancement of optical phenomena such as Raman scattering, second harmonic generation, fluorescence, etc.

Light manipulation using SPPs can be effectively reduced from three to two dimensions and SPPs also allow scaling down optical and electronic devices to nanometric dimensions as well as providing a great deal of flexibility in photonic integration in all-optical circuits. Innovative integrated components combining photonics and electronics can therefore be devised and the manipulation of optical signals on a sub-wavelength scale is made possible.

Although the Winter College on Optics is geared for researchers from developing countries, students and post-doctoral scientists from developed countries may also attend.

The Winter College on Optics also includes an ICTP Preparatory School, from 30 January to 3 February, for a limited number of selected participants. The Preparatory School provides background tutorials and exercises in electromagnetism, general optics, and Fourier transforms.
