Nano drone bioinspiré à ailes vibrantes

Marguerite de la Bigne, Mathieu R Colin, Sofiane Ghenna, Eric Cattan, Grondel Sébastien, Olivier Thomas

Cet exposé montre les derniers travaux sur le dimensionnement d’un nanodrone bio-inspiré à ailes vibrantes. Cette étude s’intègre à un projet qui a pour objectif de faire décoller le plus petit drone au monde. Son originalité réside dans les techniques de fabrication utilisées, puisque le drone est…

Highly Efficient Terahertz Spintronic Emitter Integrated with Optimized Photonic Crystal

Pierre Kolejak, Geoffrey Lezier, Lukas Halagacka, Zuzana Gelnarova, Jean-Francois Lampin, Nicolas Tiercelin, Mathias Vanwolleghem, Kamil Postava

Spintronic terahertz emitters are new to the terahertz source family. They are broad-spectrum and gapless unlike traditional sources involving semiconductors and nonlinear crystals. Moreover, they can emit intense electromagnetic fields strong enough for nonlinear terahertz application, but on the…

Traveling wave photomixers based on low-temperature-grown Gallium Arsenide reaching 50 mA/W under 1550 nm CW illumination

Charbel Tannoury, Vanessa Avramovic, Etienne Okada, Christophe Coinon, Jean-Francois Lampin, Emilien Peytavit

In this work we present an original design of a traveling-wave photomixer (TWP) based on low-temperature-grown GaAs layer (LT-GaAs) optimized for 1550 nm wavelength excitation. The optical wave is absorbed in the LT-GaAs through an integrated silicon nitride-based waveguide. The optical waveguide…

Split-ring resonators imaged by THz s-SNOM

Cristiane Santos, Theo Hannotte, Louis Thomas, Benjamin Walter, Melanie Lavancier, Sophie Eliet, Marc Faucher, Jean-Francois Lampin, Romain Peretti

Split-ring resonators (SRRs) are one of the most common building blocks to design metamaterials operating over a large range of frequencies in the electromagnetic spectrum. Here we acquire s-SNOM images with high signal-to-noise ratio on SRRs by scattering-type scanning near-field optical…

A multiline InP-TRL kit for sub-mmWave characterization of InP-HEMT

R. Younes, Nicolas Wichmann, Sylvie Lepilliet, Guillaume Ducournau, S. Bollaert

We investigate the development of on-wafer multiline Thru-Reflect-Line calibration kits to enable transistor characterization beyond 110 GHz. The final objective is to measure the S parameters of a HEMT having a very high cut-off frequency (up to THz range). A first kit design shows that the use of…

Noise analysis, noise reduction and covariance estimation for Time domain Spectroscopy

Elsa Denakpo, Theo Hannotte, Melanie Lavancier, Sophie Eliet, Romain Peretti

Time domain spectroscopy is now 30 year old and spread more and more along many fields of analytical sciences. The specificity of this technique reads in its name: measurements are not done in the frequency domain using a dispersive element, but in the time domain. One of the consequences is that…

Complex refractive index determination of PTFE, TPX and polypropylene windows for TeraHertz broadband spectroscopy

J. Bichon, A. Pillet, A. Sklia, D. Petitprez, Romain Peretti, S. Eliet

We perform TeraHertz characterization of three low-loss polymer candidates, i.e. polytetrafluoroethylene, polymethylpentene, and polypropylene, to choose the material with the proper opto-mechanical properties for aerosol and gas broadband spectroscopy cell windows. Samples are analyzed with the…

On the influence of water on THz vibrational spectral features of molecular crystals

Sergey Mitryukovskiy, Danny Vanpoucke, Theo Hannotte, Melanie Lavancier, D. Hourlier-Bahloul, Goedele Roos, Romain Peretti

The collective vibrations in molecular crystals can be probed using terahertz spectroscopy, providing unique characteristic spectral fingerprints. However, the association of the spectral features to the crystal conformation, crystal phase and its environment is a difficult task. We present a…
