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. ...

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 ...

Near-field polarization measurements based on two arbitrary, orthogonal optical field components

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

Using a multi-heterodyne scanning near-field optical microscope, we detect two arbitrary, orthogonal components of the near field. A numerical treatment of the experimental data allows the retrieval of the transverse and longitudinal components of the mode ...

Narrowband optical interactions in a plasmonic nanoparticle chain coupled to a metallic film

Olivier Martin, Daniele Brunazzo

We study the coupling of localized surface plasmon (LSP) and surface-plasmon polariton (SPP) modes in a system composed of a metallic nanoparticle chain separated from a thin metallic film by a dielectric spacer. The thickness of such a spacer influences t ...
