Milestone papers

This page is currently being developped (May 2018); it will include some of our key papers that have advanced the field of plasmonics and nanophotonics. Some are highhly cited... some are less cited... but we find them important nonetheless and we hope you will find some useful and inspiring material here.

Over the years, we have developped many algorithm for computing light interaction with nanostructures. This was the very first one, developped during my PhD. The method bares some similarities with quantum mechanics, since it combines iteratively the solution of Dyson's equation with that of Lippmann-Schwinger. The approach assumes that the scatterer is embedded into an infinite homogeneous background, Fig. (a). It can be used to compute a broad variety of geometries, like the tilted mirror illuminated by a plane wave, leading to a standing wave in front of the mirror, Fig. (b).

This is the very first paper where it was demonstrated that you can break the diffraction limit in the near-field of a nanoscopic object. Although this has now become a perfectly accepted idea, when it was published in 1995, this paper generated quite a lot of discussion and even some comments from a few well-known scientists, who could not believe that the optical field just above a low-dimension object can perfectly reproduce the shape of this object. Here we used the letter "F" as object and plotted the field intensity using what was then the state-of-the-art software... data visualization has quite progressed since!
 
Controlling and tuning strong optical field gradients at a local probe microscope tip apex

The ligthning rod effect had been known since the work of Benjamin Franklin in 1794. However, in this paper, we unveiled the dramatic enhancement produced - at optical frequencies - by a tungsten tip. This was the golden era of scanning tunneling microscopes, where such tips were routinely used. The typical geometry is shown in Fig. (a), while Figs. (b) and (c) illustrate the dramatic influence of the incident polarization on the field intensity enhancement just below the tip apex.
