Programmable Multistable Mechanisms for Safe Surgical Puncturing

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

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

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

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 ...

Mechanisms of Fano Resonances in Coupled Plasmonic Systems

Olivier Martin, Benjamin Gallinet, Andrea Lovera

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, Benjamin Gallinet, Andrea Lovera, 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 ...

Controlling and utilizing optical forces at the nanoscale with plasmonic antennas

Olivier Martin, Andrea Lovera

Plasmonic dipole antennas are powerful optical devices for many applications since they combine a high field enhancement with outstanding tunability of their resonance frequency. The field enhancement, which is mainly localized inside the nanogap between b ...
