We investigate the focusing of light by single latex microspheres illuminated by a collimated beam. Measurements are performed with a fast scanning confocal microscope in detection mode, where the detection pinhole defines a diffraction-limited observation volume that is scanned in three dimensions over the microsphere vicinity. From the collected stack of images, we reconstruct the full 3 dimensional photonic nanojet beam created by the microsphere.
Remarkably, we measure spot sizes as small as 270 nm FWHM for a wavelength of 520 nm. The beam keeps a subwavelength FWHM over a propagation distance of more than 3 micrometers, displaying all the specificities of a photonic nanojet.

By clicking on the “published papers” link on the left, you’ll be redirected to the ResearcherID webpage, which contains an additional link to the ResearcherID new features “Labs”. Alternatively, this can be accessed directly by http://labs.researcherid.com/mashlets/rid/?rid=A-5657-2008
The most intriguing feature is the citing articles network, which enables you to visualize who’s citing your work. Sorting can be done by person, institutions, countries, years…
At the end, you’re on procrastinating for a few tens of minutes more, and can proudly (?) display a “citing network worldmap” as mine:
PS: my geekiness is getting worse each day…
