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.

Still nothing concrete. That’s not really surprising, the thing that amazes me is that the movement is still alive.

Just block it : Yes we can !

5 Février 2009 , Rédigé par JW Publié dans #Fancy lab

As decided by a large majority of university staff and students, the campus on St Jerome will be blocked one day per week, starting Monday Feb 09.
This shall last as long as the government does not give any answer to our claims concerning status, CNRS future, fundings and employment.
