Toward Bloch Surface Wave-Assisted Spectroscopy in the Mid-Infrared Region

Hans Peter Herzig, Grégoire Maxime Smolik, Nicolas Maxime André Descharmes

We present the first observation of Bloch surface waves in the mid-infrared spectral range. Bloch surface waves are electromagnetic states that can propagate at the interface between a continuous dielectric medium and a periodic stack of materials. We desi ...

Observation of Bloch Surface waves in the mid-infrared spectral range

Hans Peter Herzig, Grégoire Maxime Smolik, Nicolas Maxime André Descharmes

We present the observation of Bloch Surface Waves in the mid-infrared spectral range. A dielectric multi-layer coating made of ZnSe and YbF3 deposited on a CaF2 substrate is designed and fabricated specifically for that purpose. The structure supports the ...

High Quality Factor Confinement Of Bloch Surface Waves At Visible Wavelengths

Hans Peter Herzig, Nicolas Maxime André Descharmes, Gaël David Osowiecki, Babak Vosoughi Lahijani, Raphaël Barbey

We report the first experimental demonstration of high quality factor confinement of Bloch surface waves at visible wavelengths. The cavities consist of planar Fabry-Perot resonators that are fabricated on top of a Bloch surface supporting substrate. This ...

Investigation of the Propagation Length of Bloch Surface Waves on One Dimensional Photonic Crystals

Hans Peter Herzig, Nicolas Maxime André Descharmes, Gaël David Osowiecki, Babak Vosoughi Lahijani

A 1D photonic crystal structure sustaining optical surface waves is investigated. The propagation length of the surface mode is studied both using an eigenmode model and a rigorous time domain solver. The two models show good convergence. Our results demon ...

Subwavelength Focusing of Bloch Surface Waves

Hans Peter Herzig, Myun Sik Kim, Nicolas Maxime André Descharmes, Babak Vosoughi Lahijani

Microsized spheres can focus light into subwavelength spatial domains, a phenomenon called photonic nanojet. Even though well studied in three-dimensional (3D) configurations, only a few attempts have been reported to observe similar phenomena in two-dimen ...
