Deep Cfht Y-Band Imaging Of Vvds-F22 Field. I. Data Products And Photometric Redshifts

We present our deep Y-band imaging data of a two square degree field within the F22 region of the VIMOS VLT Deep Survey. The observations were conducted using the WIRCam instrument mounted at the Canada-France-Hawaii Telescope (CFHT). The total on-sky time ...

All-fibered chalcogenide based continuous-wave parametric amplification in the mid-infrared

Camille Sophie Brès, Davide Grassani, Svyatoslav Kharitonov, Sida Xing

We demonstrate parametric amplification around 2 μm in a dispersion engineered tapered microstructured chalcogenide fiber. Almost 5 dB of signal amplification was achieved by 125 mW coupled power from a thulium-doped fiber pump laser. ...

Advanced optical components for mid-infrared applications

Grégoire Maxime Smolik

The mid-infrared wavelength range, defined from 2.5 um to 25 um is of a high scientific and technological interest. One of its main application field is in spectroscopy, since these wavelengths coincidewith the fundamental rotational-vibrational modes of m ...

Nanoplasmonic mid-infrared biosensor for in vitro protein secondary structure detection

Giovanni Dietler, Hilal Lashuel, Hatice Altug, Francesco Simone Ruggeri, Dordaneh Etezadi, John Blaine Warner IV

Plasmonic nanoantennas offer new applications in mid-infrared (mid-IR) absorption spectroscopy with ultrasensitive detection of structural signatures of biomolecules, such as proteins, due to their strong resonant near-fields. The amide I fingerprint of a ...

Recherche de fragments de plastique dans les sédiments profonds du Léman

Luiz Felippe De Alencastro, Florian Faure

A growing number of studies focusing on microplastics (plastic particles smaller than 5 mm) show this issue affects all environmental matrices and compartments, and suspicions grow as to their toxicity. In this context, the Commission Internationale pour l ...

A complete census of Herschel-detected infrared sources within the HST Frontier Fields

Jean-Paul Richard Kneib, Benjamin Yvan Alexandre Clement, Johan Richard

We present a complete census of all Herschel-detected sources within the six massive lensing clusters of the HST Frontier Fields (HFF). We provide a robust legacy catalogue of 263 sources with Herschel fluxes, primarily based on imaging from the Herschel L ...

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. ...

Binary subwavelength structures that act simultaneously as antireflective and diffractive structure for the mid-infrared wavelength range

Hans Peter Herzig, Grégoire Maxime Smolik

We present a single-layer of binary subwavelength structures designed to reduce Fresnel reflections at an interface while providing an efficient diffractive function. ...

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 ...
