Study of the nanostructured active cavities with photonic bandgaps, Etude des cavités actives dans les nanostructures périodiques à gap de photons

Abdallah El Soussi

In this thesis, a study of periodic microstructures and their applications to optical modulation by acoustical waves is presented. More specifically, it deals with opto-mechanical coupling in phoXonic crystal cavities. This study shows how the perturbation theory provides an efficient tool to…, Dans cette thèse, une étude des microstructures périodiques et de leurs applications à la modulation optique par ondes acoustiques est présentée. Plus spécifiquement, le sujet traite du couplage opto-mécanique dans les cavités des cristaux phoXoniques. Cette étude montre comment la théorie des…

Real time fault detection on in-vehicle power line networks based on power line communication

Navish Lallbeeharry, Virginie Degardin, Pierre Degauque, Christophe Trebosc

Real time detection of intermittent or permanent faults which could appear on wired networks becomes a critical issue. Fault detection and localization methods are often based on reflectometry techniques but they need the implementation of dedicated devices. Furthermore, since they often use a wide…

Direct observation of V-pit induced vertical n-type columns disrupting vertical breakdown of AlGaN/GaN-HEMT heterostructures on Si

S Besendörfer, E Meissner, F Medjdoub

High electron mobility transistors (HEMTs) based on AlGaN/GaN heterostructures on silicon are stateof-the-art commercial power devices on the basis of nitrides. Performance and reliability of suchdevices are hampered by the presence of various defects. However, the relation between the natureof…

Cryptosporidium Genotypes and Subtypes in Diarrheal Dairy Calves in France

Mohamed Mammeri, Aurélie Chevillot, Ilham Chenafi, Myriam Thomas, Christine Julien, Isabelle Vallée, Bruno Polack, Jérôme Follet, Karim Adjou

Little is known about the genetic of Cryptosporidium in calves in eastern regions of France. The aim of this study was to detect and isolate Cryptosporidium spp. in faecal samples from naturally infected pre-weanedcalves (≤ 45 days-old) in France. A total of 35 diarrhoeic pre-weaned calves faecal…

[Invited] Towards higher voltage in III-Nitride devices

F Medjdoub

GaN-based switches will offer greater efficiency, power handling, and compactness as compared to the well-established, widely available silicon MOSFET power devices-all factors that are critical to meeting the needs of today's systems. However, the vertical breakdown voltage of GaN-on-silicon…
