Optimization of photoswitch constituted of a coplanar line introducing an interdigitated MSM photodetector

Abdelkader Aissat, M. El Besseghi, Didier Decoster

In this paper we present the optimization of photoswitches constituted of a coplanar line introducing interdigitated MSM photodetectors in the central strip. The reflection and the transmission coefficients are studied with the aim of highlighting the influence of different geometrical parameters…

Electrooptic and converse-piezoelectric properties of epitaxial GaN/Si structures for optoelectronic applications

Mireille Cuniot-Ponsard, Irma Saraswati, S.-M. Ko, Mathieu Halbwax, Y.-H. Cho, N.-R. Poespawati, El Hadj Dogheche

In order to take advantage in all-optic optoelectronic devices, we have investigated the optical and piezoelectric properties of GaN films deposited on (111) silicon. Films are epitaxially grown by MOCVD, thanks to a buffer made of (Al, Ga) N intermediate layers [1]. Structural properties of GaN…

UWB System Based on the M-OAM Modulation in IEEE.802.15.3a Channel

Khadija Hamidoun, Raja Elassali, Yassin El Hillali, Khalid Elbaamrani, Atika Rivenq, F. Elbahhar

Known for many years but unexploited in the field of communications, ultra wideband systems (UWB) can be a solution to the saturation of the frequency bands. The advantage of such systems is that they are inexpensive in energy because of the limitations imposed by the standard. Our work is to…

Near-field Microwave Microscopy for Liquid Characterization

Sijia Gu, Kamel Haddadi, Tuami Lasri

A near-field microwave microscopy platform for the characterization of liquids is proposed. The technique is based on the association of a network analyzer and an evanescent microwave coaxial probe. The major feature of the system proposed is the development of a broadband tunable matching network…

Theoretical and experimental investigation of Lamb waves characteristics in AlN/TiN and AlN/TiN/NCD composite membranes

Ali Soltani, Abdelkrim Talbi, J-C Gerbedoen, Jean-Claude de Jaeger, Philippe Pernod, V. Mortet, A. Bassam

In this study, we present a theoretical and experimental investigations of the zero order quasi-symmetric (S0) Lamb waves mode propagating in AlN/TiN and AlN/TiN/NCD composite membranes. Theoretical analysis of S0 mode characteristics shows that The AlN/TiN membrane enables to achieve smooth…

Optomechanic interaction in a corrugated phoxonic nanobeam cavity

Mourad Oudich, Said El-Jallal, Yan Pennec, Bahram Djafari-Rouhani, Jordi Gomis-Bresco, Daniel Navarro-Urrios, Clivia M. Sotomayor Torres, Alejandro Martínez, Abdelkader Makhoute

The interaction between phonons and photons is investigated theoretically in a phoxonic cavity inside a corrugated nanobeam waveguide presenting band gaps for both electromagnetic and elastic waves. The structure is made by drilling periodic holes on a silicon nanobeam with lateral periodic stubs…

Transport properties of CdSe nanocrystal superlattice

Pierre Capiod, Maxime Berthe, B. Grandidier, Wiel Evers, Daniel Vanmaekelbergh

Two-dimensional materials exhibit exotic electronic properties and high specific surface areas that make them unique to investigate novel physical phenomena. In addition, their two-dimensional geometry is directly compatible with established design and processing approaches from the semiconductor…

Silicon nanotweezers inside liquid for the real time characterization of DNA degradation under radiotherapy treatment

Grégoire Perret, T. Lacornerie, V. Kumemura, N. Lafitte, H. Guillou, L. Jalabert, E. Lartigau, T. Fujii, Fabrizio Cleri, H. Fujita, Dominique Collard

Tumor cell killing by γ-ray beams in radiotherapy is currently based on a rather empirical understanding of the basic mechanisms and effectiveness of DNA damage by radiation. On the other hand, the mechanical behavior of DNA, e.g., sequence-sensitivity, elastic vs. plastic response, is well…

Control of the ionization state of three single donor atoms in silicon

B. Voisin, M. Cobian, X. Jehl, M. Vinet, Yann-Michel Niquet, Christophe Delerue, Silvano de Franceschi, M. Sanquer

By varying the front-gate and the substrate voltages in a short silicon-on-insulator trigate field-effect transistor, we control the ionization state of three arsenic donors. We obtain good quantitative agreement between three-dimensional electrostatic simulations and experiment for the control…
