Actually, this paper was written in March 2007, revised version accepted for publication in September 2007, and finally published in April 2009 !! Never got a decent explanation with such a delay. So this explains why the reference list therein is mostly already obsolete now, with no citations to papers of late 2007 and 2008.

Latest paper published : 3-axis sub-lambda confinement with nanojets

25 Mai 2009 , Rédigé par JW Publié dans #Recent research work

Published in Optics Express, freely downloadable at :


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.
