Demultiplexing of terahertz wireless links using a leaky-wave antenna

J. Ma, N. Karl, Sara Bretin, Guillaume Ducournau, D. Mittleman

We demonstrate multiplexing and demultiplexing for terahertz wireless data links in the 300 GHz band. Demultiplexing of real-time data streams at different carrier frequencies with different data rates is presented, and real-time bit error rates are characterized.

Ultra-thin InGaAs-MSM photodetectors for THz optoelectronics applications

Maximilien Billet, Yann Desmet, Christophe Coinon, Guillaume Ducournau, X. Wallart, Jean-Francois Lampin, Emilien Peytavit

We present a new design of InGaAs metal-semiconductor-metal (InGaAs-MSM) photodetectors placed in optical resonant cavities in order to reduce inter-electrode spacing while keeping a high photoresponse. Its static and dynamic photoresponse properties have been measured by means of a photomixing…

Progress in continuous wave THz molecular laser optically pumped by a quantum cascade laser

Antoine Pagies, Guillaume Ducournau, Jean-Francois Lampin

We have demonstrated a new approach to realize a continuous wave room temperature THz laser source: a low-pressure molecular gas is optically pumped by a solid-state mid-infrared source. A tunable quantum cascade laser allows to have access to transitions that are not accessible to CO 2 lasers.…

Ultrafast LT-GaAs photoconductors based on a Fabry-Pérot cavity designed for 1550 nm wavelength illumination

Maximilien Billet, Yann Desmet, Fuanki Bavedila, Guillaume Ducournau, Stefano Barbieri, Jean-Francois Lampin, Emilien Peytavit

We study low-temperature-grown GaAs (LT-GaAs) based ultrafast Fabry-Pérot cavity photoconductors, designed for THz optoelectronics applications using 1550 nm pulsed lasers. We present here, as a proof of concept, the under-sampling of continuous RF waves up to 67 GHz.

Cost effective laser structuration of optical waveguides on thin glass interposer

Jean-Marc Boucaud, Folly-Eli Ayi-Yovo, Quentin Hivin, Matthieu Berthomé, Cédric Durand, Frédéric Gianesello, D. Bucci, Guillaume Ducournau, J.F. Robillard, Jean-Emmanuel Broquin, Emmanuel Dubois

In order to enhance electro-optical system-in-package capabilities for silicon photonics, a cost effective fabrication process for optical waveguides integration on thin glass substrate interposer is demonstrated. Firstly, a femtosecond laser ablation coupled with a hydrofluoric acid etching is…

Probing Frontier Orbital Energies of {Co 9 (P 2 W 15 ) 3 } Polyoxometalate Clusters at Molecule–Metal and Molecule–Water Interfaces

Xiaofeng Yi, Natalya V. Izarova, Maria Stuckart, David Guérin, Louis Thomas, Stéphane Lenfant, Dominique Vuillaume, Jan van Leusen, Tomas Duchon, Slavomir Nemsak, Svenja D. M. Bourone, Sebastian Schmitz, Paul Kögerler

Functionalization of polyoxotungstates with organoarsonate co-ligands enabling surface decoration was explored for the triangular cluster architectures of the composition [CoII9(H2O)6(OH)3(p-RC6H4AsVO3)2({\alpha}-PV2WVI15O56)3]25-({Co9(P2W15)3}, R = H or NH2), isolated as Na25[Co9(OH)3(H2O)6(…

Magnetic Resonance with Squeezed Microwaves

A. Bienfait, P. Campagne-Ibarcq, A. h. H Kiilerich, Xin Zhou, S. Probst, J.  J Pla, T. Schenkel, D. Vion, Daniel Estève, J.  J. l. Morton, K. Moelmer, P. Bertet

Vacuum fluctuations of the electromagnetic field set a fundamental limit to the sensitivity of a variety of measurements, including magnetic resonance spectroscopy. We report the use of squeezed microwave fields, which are engineered quantum states of light for which fluctuations in one field…
