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. ...

Excitation and Reemission of Molecules near Realistic Plasmonic Nanostructures

Olivier Martin, Andreas Kern

The enhancement of excitation and reemission of molecules in dose proximity to plasmonic nanostuctures is studied with special focus on the comparison between idealized and realistically shaped nonostructures. Numerical experiments show that for certain ap ...

Light scattering by an array of electric and magnetic nanoparticles

Olivier Martin, Benjamin Syriam Garcia

Light scattering by an array of alternating electric and magnetic nanoparticles is analyzed in detailed. Specific geometrical conditions are derived, where such an array behaves like double-negative particles, leading to a suppression of the backscattered ...

Ultrathin waveguides for Bloch Surface Waves: near-field analysis of propagation and polarization

Tristan Sfez, Hans Peter Herzig, Olivier Martin, Daniele Brunazzo, Libo Yu

We demonstrate that an ultrathin ridge (< lambda/10) can guide Bloch surface waves in a dielectric multilayer. The propagation and polarization properties of the guided modes are investigated with a multi-heterodyne scanning near-field optical microscope. ...

Interplay of plasmon resonances in binary nanostructures

Olivier Martin, Yi Wang, Jing Li

By introducing the difference permittivity ratio eta=(epsilon (2)-epsilon (0))/(epsilon (1)-epsilon (0)), the Green matrix method for computing surface plasmon resonances is extended to binary nanostructures. Based on the near field coupling, the interplay ...

Optical trapping and sensing with plasmonic dipole antennas

Olivier Martin

In this work, we study how to use a plasmonic dipole antenna as a multifunctional nanodevice for surface-enhanced Raman spectroscopy (SERS), localized surface plasmon resonance (LSPR) -based sensing and optical trapping. An analytical model is implemented ...

Bloch surface waves in ultrathin waveguides: near-field investigation of mode polarization and propagation

Tristan Sfez, Hans Peter Herzig, Olivier Martin, Daniele Brunazzo, Libo Yu, Francesco Michelotti

In this work, we use a multi-heterodyne scanning near-field optical microscope to investigate the polarization and propagation of Bloch surface waves in an ultrathin (similar to lambda/10) ridge waveguide. First, we show that the structure sustains three s ...

Guided Bloch Surface Waves on Ultrathin Polymeric Ridges

Tristan Sfez, Hans Peter Herzig, Olivier Martin, Daniele Brunazzo, Francesco Michelotti

We present a direct evidence of Bloch surface waves (BSWs) waveguiding on ultrathin polymeric ridges, supported by near-field measurements. It is demonstrated that near-infrared BSWs sustained by a silicon-based multilayer can be locally coupled and guided ...
