Micro-optical elements are optical elements having size or details in the range of the micrometer scale. The emergency of such elements is strongly linked to the development made in the fabrication techniques during the nineties to follow the still actual ...

We experimentally demonstrate surface excitation of hybridized plasmons in metallic nanocavities. We developed a quasi-static model connecting this observation to plasmonic antenna behavior for extraordinary light transmission effect. ...
Extraordinary light transmission effect through Fabry-Perot cavities in 3D plasmonic cystals consisting of two physically separated metallic nanohole and nanodisk array layers is demonstrated. These cavity resonances are highly sensitive to refractive inde ...
It has been theoretically predicted and experimentally shown that circular coaxial aperture arrays have higher transmissivities with respect to simple circular ones. This observation is mainly attributed to the propagating waveguide modes supported by the ...
We report on the installation of fast polarizers for ECRH injection and ECE diagnostics, in the TCV tokamak. The main goal is to change the polarization during a plasma shot and react to changing conditions such as: plasma current and position, ECRH inject ...
The extraordinary light transmission effect (EOT) through sub-wavelength nanoapertures in opaque metal films has lead to observation of a wide variety of exciting new optical phenomena. This remarkable effect is generally related to the interaction of the ...
Fast and sensitive virus detection techniques which can be rapidly deployed at multiple sites are essential to prevent and control future epidemics and bioterrorism threats In this Letter we demonstrate a label free optofluidic nanoplasmonic sensor that ca ...
We experimentally demonstrate that hybridized nanocavities in optically thick metal films radiate in coherence, and act as an efficient single-polarized plasmonic nano-antenna array. We employ propagating and localized plasmons to enhance polarization cont ...
We present a method to image Jones vector by use of digital holography. We demonstrate that with a single hologram acquisition, the method allows to image and to calculate Jones vector and derive the polarization parameters. The principle consists in using ...
We report the experimental observation of temporal vector soliton propagation and collision in a linearly birefringent optical fiber. To the best of the authors’ knowledge, this is both the first demonstration of temporal vector solitons with two mutually ...
