Polymer photonic crystal membrane for thermo-regulating textile

Salim Assaf, Mohamed Boutghatin, Yan Pennec, V. Thomy, Alexander Korovin, A. Treizebre, Michèle Carette, Abdellatif Akjouj, Bahram Djafari-Rouhani

We study numerically the absorption and scattering properties of a polymer photonic membrane to thermoregulate the human body microclimate which corresponds to the area between the skin and a textile. We first show that the structuration of the absorbing photonic membrane with air holes leads to a...

Active control of the transmission of Lamb waves through an elastic metamaterial

W. Wang, B. Bonello, Bahram Djafari-Rouhani, X. Fang, Yan Pennec, J. Zhao, Y. Jin

We have numerically investigated the transmission of an antisymmetric Lamb wave through a line of silicon pillars erected onto a homogeneous silicon plate when the frequency is tuned to a resonant frequency of the pillars. For either a bending mode or a compressional mode, the resonators emit in...

Scintillators from solution-processable perovskite halide single crystals or quantum dots: the good, the bad, and the ugly

M. D. Birowosuto, F. Maddalena, A. Xie, M. E. Witkowski, M. Makowski, W. Drozdowski, Philippe Coquet, Christophe Dujardin, Cuong Dang

Here we report X- and gamma-ray scintillation properties from solution-processable perovskite (SPP) halide single crystals and quantum dots. We tune the properties of single crystals by replacing the cation, changing the organic ammonium cation spacer, and varying the halide anion. For quantum dots...

High speed mid-IR quantum cascade detector at room temperature

G. Quinchard, C. Mismer, V. Trinite, A. Evirgen, A. Larrue, M. Hakl, Jean-Francois Lampin, Emilien Peytavit, S Barbieri, A. Delga

We present a high-speed antenna enhanced Quantum Cascade Detector at 10.3μm. By using a coherent detection scheme and thin InGaAs/AlInAs heterostructure embedded in metal-metal patch antenna, we demonstrate a heterodyne response up to 67 GHz at room temperature.

Low-Temperature-Grown Gallium Arsenide Photoconductors with Photoresponse Reaching 25 mA/W under 1550nm Cw Excitation

Charbel Tannoury, Maximilien Billet, Christophe Coinon, Jean-Francois Lampin, Emilien Peytavit

We show in this communication that photoconductors based on GaAs grown at low temperature can exhibit photoresponses as high as 25 mA/W under continuous-wave 1550-nm-wavelength illumination. It is achieved by using an optical Fabry-Pérot cavity in order to improve the external quantum efficiency...

Subcellular imaging during single cell mechanical characterization

Deniz Pekin, Gregoire Perret, Quentin Rezard, Jean Claude Gerbedoen, Samuel Meignan, Dominique Collard, Chann Lagadec, Mehmet Tarhan

We report a method for combining confocal microscopy with single-cell mechanical characterization. This method allows investigating the effect of subcellular deformation (e.g. membranes, cytoplasm, cytoskeleton and organelles as endoplasmic reticulum, mitochondria, and nucleus) on cell mechanical...
