Ferroelectrics based absorbing layers

Jianping Hao, Véronique Sadaune, Ludovic Burgnies, Didier Lippens

We show that ferroelectrics-based periodic structure made of BaSrTiO3 (BST) cubes, arrayed onto a metal plate with a thin dielectric spacer film exhibit a dramatic enhancement of absorbance with value close to unity. The enhancement is found around the Mie magnetic resonance of the Ferroelectrics…

All optical method for investigation of spin and charge transport in semiconductors : combination of spatially and time-resolved luminescence

Fabian Cadiz, Philippe Barate, D. Paget, Denis S Grebenkov, J.P. Korb, A.C.H. Rowe, Thierry Amand, S. Arscott, Emilien Peytavit

A new approach is demonstrated for investigating charge and spin diffusion as well as surface and bulk recombination in unpassivated doped semiconductors. This approach consists in using two complementary, conceptually related, techniques, which are time-resolved photoluminescence (TRPL) and…

Direct path detection algorithm in multiple input single output configuration for transport applications

Kobenan Ignace Kossonou, Yassin El Hillali, Michael Bocquet, Atika Rivenq, Jamal Assaad

This paper introduces a novel technique that exploits cross-correlation properties of near-orthogonal pseudonoise (PN) codes to estimate the time of arrival of the direct path signal for Multiple Input Single Output (MISO) applications. Indeed, multipath are a source of error in the time…

High-definition television transmission at 600 GHz combining THz photonics hotspot and high-sensitivity heterodyne receiver

Guillaume Ducournau, Fabio Pavanello, Alexandre Beck, L. Tohme, S. Blin, P. Nouvel, Emilien Peytavit, Mohamed Zaknoune, P. Szriftgiser, Jean-Francois Lampin

A 600 GHz data transmission using the combination of a photonic emission using a uni-travelling carrier photodiode and an electronic detection is investigated. A high-definition television transmission at this carrier frequency with a very low power at the receiver is reported. Only 10 nW of…

Interferometric Near-field Microwave Microscopy Platform for Electromagnetic Micro-analysis

Kamel Haddadi, Jaouad Marzouk, Sijia Gu, S. Arscott, Gilles Dambrine, Tuami Lasri

We report an original near-field microwave microscope based on an interferometric technique for dielectric characterization in liquid media. The instrumentation combines a vector network analyzer, an interferometry-based matching network and dedicated evanescent microstrip probes fabricated in…

Cascaded Brillouin fibre lasers coupled to unitravelling carrier photodiodes for narrow linewidth terahertz generation

Guillaume Ducournau, Denis Bacquet, P. Szriftgiser, Fabio Pavanello, Emilien Peytavit, Mohamed Zaknoune, Alexandre Beck, Jean-Francois Lampin

Narrow linewidth terahertz (THz) generation using a cascaded Brillouin fibre laser structure and a unitravelling carrier photodiode is investigated. Using two distributed feedback lasers separated by > 1 THz with 1 MHz initial linewidth, the use of the cascaded Brillouin laser greatly increases…

ZnO nanowires and PbS quantum dots for third-generation solar cells

Basma El Zein, Mutalifu Abulikemu, Erkki Alarousu, Omar F. Mohammed, Enrico Traversa, El Hadj Dogheche

Nanowires and quantum dots hold promising potency to enhance the performance of solar cells by improving light absorption, light trapping, exciton generation, and photoexcited-carrier collection. Quantum dot sensitized solar cells consist of three components: semiconductor quantum dots, one…

Caractérisation par acoustique picoseconde des propriétés mécaniques du PZT déposé en couches minces pour des applications MEMS

Fabrice Casset

Les MEMS sont aujourd'hui une réalité économique et sont d'ores et déjà utilisés dans un grand nombre d'objets de notre quotidien. Ces composants peuvent utiliser un actionnement piézoélectrique, notamment à base de PZT déposé en couches minces, du fait de son fort coefficient…
