Surface-based luminescence measurement substrate

Nicolas Maxime André Descharmes, Raphaël Barbey

Surface-based measurement substrate including: • - at least one optical cavity layer (7); • - a first optical mirror (9) and a second optical mirror (11), the first and second optical mirrors enclosing the optical cavity layer and defining an optical cavit ...

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 ...

Investigation of the Propagation Length of Bloch Surface Waves on One Dimensional Photonic Crystals, 2018 International Conference on Optical MEMS and Nanophotonics (OMN)

Hans Peter Herzig, Gaël David Osowiecki, Nicolas Maxime André Descharmes, 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 ...

High Quality Factor Confinement Of Bloch Surface Waves At Visible Wavelengths

Hans Peter Herzig, Gaël David Osowiecki, Nicolas Maxime André Descharmes, 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 ...

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 ...

Hybrid PDMS/glass microfluidics for high resolution imaging and application to sub-wavelength particle trapping

Romuald Houdré, Nicolas Maxime André Descharmes, Mario Lucien Henri Tonin

We demonstrate the fabrication of a hybrid PDMS/glass microfluidic layer that can be placed on top of non-transparent samples and allows high-resolution optical microscopy through it. The layer mimics a glass coverslip to limit optical aberrations and can ...
