I will be at the next international conference on surface plasmon photonics, to be hold June 21-26 in Amsterdam : http://www.spp4.org/
Meet you after my talk O-02 “Merging fluorescence correlation spectroscopy and plasmonics:
characterizing nanostructures for high rate high efficiency single molecule detection” on Monday 22nd, 10AM.

We show that latex microspheres are able to confine light in a three-dimensional region of subwavelength dimensions. A simple configuration, not involving resonances, allows to reach an effective volume as small as 0.6 (lambda/n)^3, hereby beating the far-field diffraction barrier. We relate this phenomenon to interferences between the field scattered by the sphere and the incident Gaussian beam.
The animated gif below shows the electric field intensity distribution while the microsphere is displaced towards the focus of the incident laser beam.
This paper was highlighted as picture of the week on Optics Infobase webpage, and (consequently?) ranked 6th out of the most downloaded OSA paper of March 2009.
We are pleased to organize the next Carl Zeiss sponsored workshop on fluorescence correlation spectroscopy and related methods. The workshop will take place at Cargese (Corsica, France) from October 12th – 16th 2009.
