Journal ArticleDOI
Giant magnetoresistance of (001)Fe/(001)Cr magnetic superlattices.
Mario Norberto Baibich,J. M. Broto,Albert Fert,F. Nguyen Van Dau,Frédéric Petroff,P. Etienne,G. Creuzet,A. Friederich,Jean Chazelas +8 more
TL;DR: This work ascribes this giant magnetoresistance of (001)Fe/(001)Cr superlattices prepared by molecularbeam epitaxy to spin-dependent transmission of the conduction electrons between Fe layers through Cr layers.

Process and system for determining the position and orientation of a vehicle, and applications
Jean Chazelas,Philippe Souchay +1 more
TL;DR: In this article, the authors propose an interrogation/response process whose particular feature is to supply, to a given interrogation, two responses which are distinguished on the one hand, by different modulating frequencies and, on the other hand, the fact that they are transmitted according to two patterns which differ in aim relative to one another.
Journal ArticleDOI
Optical signal processing in Radar systems
S. Tonda-Goldstein,Daniel Dolfi,Aymeric Monsterleet,S. Formont,Jean Chazelas,Jean-Pierre Huignard +5 more
TL;DR: In this article, two optical architectures illustrate functions specific to optical processing of microwave signals, i.e., time-delay-based processing and arbitrary waveform generation of large frequency bandwidth signals.
Journal ArticleDOI
Improving thermal stability of opto-electronic oscillators
M. Kaba,H.-W. Li,Afshin S. Daryoush,Jean-Pierre Vilcot,Didier Decoster,Jean Chazelas,Géraud Bouwmans,Yves Quiquempois,Francois Deborgies +8 more
TL;DR: In this article, the authors provide an overview of close-in carrier phase noise and temperature stability of various oscillators in microwave systems, using acoustic, electromagnetic, and optical technologies.
Journal ArticleDOI
Stimulated Brillouin scattering for microwave signal modulation depth increase in optical links
TL;DR: In this article, the authors used stimulated Brillouin scattering (SBS) that occurs in optical fibres to deplete the carrier and leave the modulation sidebands unchanged, achieving a modulation depth gain of >20.
