Milliwatt-level power generated in the sub-terahertz range by photomixing in a metal-metal resonant cavity GaAs photoconductor

Emilien Peytavit, Sylvie Lepilliet, Francis Hindle, Christophe Coinon, Tahsin Akalin, Guillaume Ducournau, Gaël Mouret, Jean-Francois Lampin

It is shown from on-wafer measurement that a continuous wave output power of 0.35 mW at 305 GHz can be generated by photomixing in a metal-metal Fabry-Pérot GaAs photoconductor.

Predicted eigenvalue threshold based spectrum sensing with correlated multiple-antennas

Kais Hassan, Roland Gautier, Iyad Dayoub, Emanuel Radoi, Marion Berbineau

In this paper, we consider the problem of sensing a primary user in a cognitive radio network by employing multiple-antennas at the secondary user. Among the many spectrum-sensing methods, the predicted eigenvalue threshold (PET) based method is a promising non-parametric blind method that can…

Milliwatt level output power generated by photomixing in a GaAs photoconductor

It is shown that a continuous wave output power of 0.35 mW at 305 GHz can be generated by photomixing in a low temperature grown GaAs photoconductor using a metallic mirror Fabry-Pérot cavity. The output power is improved by a factor of about 100 as compared to the previous works on GaAs…

Cavity-type hypersonic phononic crystals

A. Sato, Yan Pennec, T. Yanagishita, H. Masuda, W. Knoll, Bahram Djafari-Rouhani, G. Fytas

We report on the engineering of the phonon dispersion diagram in monodomain anodic porous alumina (APA) films through the porosity and physical state of the material residing in the nanopores. Lattice symmetry and inclusion materials are theoretically identified to be the main factors which control…

Electro-elastic moduli and frequency dependence of KN single crystal

R Rouffaud, F. Levassort, M. Pham-Thi, E. Leveugle, Anne-Christine Hladky

— Functional properties of KNbO 3 single crystal are characterized. Large polydomain plates cutted from an as-grown KNbO 3 crystal (oriented along [001] c (45°-cut) direction) are used. At the fundamental resonance (10 MHz), thickness coupling factor is 65% and frequency dependence is measured with…

New Passenger Services in Railway Stations Based on Mode Group Diversity Multiplexing Optical Fiber Communications

Dafa Loum, Charles Tatkeu, Iyad Dayoub, Marc Heddebaut, Jean-Michel Rouvaen

Nowadays, because of its wide bandwidth and high communication capability, the optical fiber is more and more used for high data rate transmission of information in railway environments. Conventionally, only one service is sent over the fiber at a time. However, many different services can be…

Role of hydration on the electronic transport through molecular junctions on silicon

N. Clement, David Guérin, S. Pleutin, S. Godey, D. Vuillaume

Molecular electronics is a fascinating area of research with the ability to tune device properties by a chemical tailoring of organic molecules. However, molecular electronics devices often suffer from dispersion and lack of reproducibility of their electrical performances. Here, we show that water…
