Optically-pumped continuous-wave terahertz sources

Philipp Latzel, Fabio Pavanello, Emilien Peytavit, Mohammed Zaknoune, Guillaume Ducournau, X. Wallart, Jean-Francois Lampin

Recently we have improved the efficiency and the output power of our optically pumped continuous-wave THz sources. These sources are based on the beating of two laser lines in a wide bandwidth photodetector. Its intrinsic nonlinear behaviour is used to produce a beatnote at the frequency difference…

Hexamolybdenum Clusters Supported on Graphene Oxide: Visible-Light Induced Photocatalytic Reduction of Carbon Dioxide into Methanol

Pawan Kumar, Harshal P. Mungse, Stéphane Cordier, Rabah Boukherroub, Om P. Khatri, Suman L Jain

Hexamolybdenum (Mo6) cluster-based compounds namely Cs2Mo6Bri8Bra6 and (TBA)2Mo6Bri8Bra6 (TBA = tetrabutylammonium) were immobilized on graphene oxide (GO) nanosheets by taking advantage of the high lability of the apical bromide ions with oxygen-functionalities of GO nanosheets. The loading of Mo6…

On the use of tracking loops for low-complexity multi-path channel estimation in OFDM systems

Huaqiang Shu, Eric Pierre Simon, Laurent Ros

—This paper treats pilot aided multi-path channel estimation with tracking loops for OFDM systems under slow to moderate fading conditions. Recent works have presented theoretical results for the tuning of second-order and third-order tracking loops in the particular context of Jakes's Doppler…

Toward quantitative modeling of silicon phononic thermocrystals

V. Lacatena, M. Haras, J.F. Robillard, S. Monfray, T. Skotnicki, Emmanuel Dubois

The wealth of technological patterning technologies of deca-nanometer resolution brings opportunities to artificially modulate thermal transport properties. A promising example is given by the recent concepts of "thermocrystals" or "nanophononic crystals" that introduce regular…

De-embedding differential noise figure using the correlation of output noise waves

Francois Graux, Francois Danneville, Yogadissen Andee, Caroline Arnaud

This paper presents a measurement technique for de-embedding the noise figure of all sorts of differential amplifiers having arbitrary common-mode rejection. It is based on the measurement of the correlation of the noise waves at the output ports of the differential amplifier. It makes use of a…

Room-Temperature, Zero-Bias Plasmonic THz Detection by Asymmetric Dual-Grating-Gate HEMT

Takayuki Watanabe, Tetsuya Kawasaki, Akira Satou, Stéphane Boubanga-Tombet, Tetsuya Suemitsu, Guillaume Ducournau, Dominique Coquillat, Wojciech Knap, Hiroaki Minamide, Hiromasa Ito, Viacheslav Popov, Yahya Moubarak Meziani, Taiichi Otsuji

We study theoretically and experimentally the plasmonic THz detection by the asymmetric dual-grating-gate HEMT at room temperature without source-to-drain bias. We derive the analytical expressions of photocurrents due to the plasmonic drag and ratchet effects, and we discuss about their frequency…

Analysis of a Phononic Crystal Constituted of Piezoelectric Layers Using Electrical Impedance Measurement

S.A. Mansoura, Pierre Marechal, Bruno Morvan, Bertrand Dubus

Active materials are investigated as a tuning possibility for phononic crystals. Electromechanical properties of piezoelectric materials electrical and mechanical variables are coupled. Thus, the propagation properties of elastic waves can be tuned using electrical impedance load connected to the…
