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 ...

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 ...

Enhancement of Second Harmonic Signal in Nanofabricated Cones

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

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 ...

Enhanced second-harmonic generation from double resonant plasmonic antennae

Olivier Martin, Andrea Lovera, Krishnan Thyagarajan, Simon Rivier

We present a novel plasmonic antenna geometry - the double resonant antenna (DRA) - that is optimized for second-harmonic generation (SHG). This antenna is based on two gaps coupled to each other so that a resonance at the fundamental and at the doubled fr ...

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 ...

Programmable Multistable Mechanisms for Safe Surgical Puncturing

David Lambelet, Arno Rogg, Simon Nessim Henein, Charles Baur, Ilan Vardi, Andrea Lovera, Thomas Jean Julien Fussinger, 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 ...

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

Olivier Martin, Jérémy Butet, Andrea Lovera

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 ...

Optical trapping at the ultimate nanoscale in the near-field of plasmonic antennas

Olivier Martin, Andrea Lovera, Andreas Kern

We study the trapping of nanoscopic objects in the near-field of plasmonic nanostructures and demonstrate experimentally that 10nm particles can be trapped in the 15nm gap of a dipole antenna. Applications for biosensing are discussed. ...

Plasmonic trapping with realistic dipole nanoantennas: Analysis of the detection limit

Olivier Martin, Andrea Lovera

We use numerical simulations based on the surface integral technique to study the detection limit of plasmonic trapping with realistic dipole antennas. The induced plasmon resonance shift due to the coupling between an antenna and a nanoparticle is studied ...
