Programmable Multistable Mechanisms for Safe Surgical Puncturing

Simon Nessim Henein, Charles Baur, Andrea Lovera, Ilan Vardi, Mohamed Gamal Abdelrahman Ahmed Zanaty, David Lambelet, Thomas Jean Julien Fussinger, Arno Rogg

We present novel medical devices for safe surgical puncturing, in particular a cannula for the treatment of retinal vein occlusion (RVO). This passive mechanical device has an adjustable stroke and exerts a puncturing force independent of operator applied ...

Enhancement of Second Harmonic Signal in Nanofabricated Cones

Anna Fontcuberta i Morral, Aleksandra Radenovic, Andrea Lovera, Oriol López Sánchez, Fabrizia Dutto, Martin Heiss

Geometrical effects in optical nanostructures on nanoscale can lead to interesting phenomena such as inhibition of spontaneous emission,(1,2) high-reflecting omnidirectional mirrors, structures that exhibit low-loss-waveguiding,(3) and light confinement.(4 ...

Detecting the trapping of small metal nanoparticles in the gap of nanoantennas with optical second harmonic generation

Olivier Martin, Andrea Lovera, Jérémy Butet

The second harmonic generation from gold nanoparticles trapped into realistic and idealized gold nanoantennas is numerically investigated using a surface integral equations technique. It is observed that the presence of a nanoparticle in the nanoantenna ga ...

Mechanisms of Fano Resonances in Coupled Plasmonic Systems

Olivier Martin, Andrea Lovera, Benjamin Gallinet

Fano resonances in hybridized systems formed from the interaction of bright modes only are reported. Despite precedent works, we demonstrate theoretically and experimentally that Fano resonances can be obtained by destructive interference between two brigh ...

Fano resonant plasmonic systems: Functioning principles and applications

Olivier Martin, Andrea Lovera, Benjamin Gallinet, Thomas Gerd Siegfried

Using a generalization of Fano formula that includes the intrinsic losses associated with metals, we retrieve the underlying modal structure that produces Fano resonances from the interference between a bright and a dark mode. This knowledge is used to det ...
