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 YbF 3 deposited on a CaF2 substrate is designed and fabricated specifically for that purpose. The structure supports the ...

A Novel 32 x 32, 224 Mevents/s Time Resolved SPAD Image Sensor for Near-Infrared Optical Tomography

Edoardo Charbon, Ivan Michel Antolovic, Chunmin Zhang, Scott Anthony Lindner, Juan Mata Pavia, Martin Wolf, Jingjing Jiang

To increase the spatial resolution of near-infrared optical tomography, we successfully designed and tested a 32×32 time-resolved SPAD image sensor with unprecedented sensitivity in the near-infrared and fast image acquisition speed. ...

Binary zero-order diffractive and anti-reflective optical elements in silicon for the mid-infrared

Hans Peter Herzig, Grégoire Maxime Smolik

We propose a novel method for the design of binary 2-level diffractive optical elements that provide an efficient diffractive function while reducing the reflectivity of a high-index interface. The structure can be fabricated with a single patterning step ...

Demultiplexing Visible and Near-Infrared Information in Single- Sensor Multispectral Imaging

Sabine Süsstrunk, Zahra Sadeghipoor Kermani, Jean-Baptiste Thomas

In this paper, we study a single-sensor imaging system that uses a multispectral filter array to spectrally sample the scene. Our system captures information in both visible and near-infrared bands of the electromagnetic spectrum. Due to manufacturing limi ...

Airborne hyperspectral sensor radiometric self-calibration using near-infrared properties of deep water and vegetation

Bertrand Merminod, Vincent Maurice Nouchi, Kevin Sylvain Barbieux

Retrieving the water-leaving reflectance from airborne hyperspectral data implies to deal with three steps. Firstly, the radiance recorded by an airborne sensor comes from several sources: the real radiance of the object, the atmospheric scattering, sky an ...

Efficient broadband parametric conversion: reaching for the Mid IR

Camille Sophie Brès, Adrien Billat

In this paper, we report recent results on the efficient generation of SWIR sources exploiting broadband wavelength conversion in silica fibers. Optimized cavity-less designs of fiber parametric amplifiers (FOPA) associated with Thulium amplification capab ...

Mid-infrared supercontinuum generation in a SiN waveguide pumped at 1.55 micron

Tobias Kippenberg, Camille Sophie Brès, Davide Grassani, Hairun Guo, Martin Hubert Peter Pfeiffer, Adrien Billat, Thibault Emmanuel North

We report supercontinuum generation extending to 3.6 micron in silicon-nitride waveguides pumped by a commercial source at 1.55 micron. The span is a bandwidth record for the platform and demonstrates its potential as mid-infrared source. ...
