Aggregated 0.3 Tbit/s link using Photonics-transmitter and micromachined flat array antenna over 315-410 GHz

Hadjer Nihel Khelil, Alexandre Renau, Pascal Szriftgiser, Yannick Roelens, Rédha Kassi, Mohammed Zaknoune, Malek Zegaoui, Joachim Oberhammer, Guillaume Ducournau

This paper presents the validation of a wireless communication link in the THz range using a photonics-based transmitter and a waveguide-fed micromachined wideband flat array antenna. Combining several carrier frequencies over the 320-400 GHz band, we show that the antenna can handle an aggregated…

Nanoparticules organiques pour le ciblage des cellules β pancréatiques dans le diabète de type 1 et de type 2, Organic nanoparticles for targeting pancreatic β cells in type 1 and type 2 diabetes

Shakila Behzadifar

Le diabète pourrait concerner jusqu’à 642 millions de personnes dans le monde d’ici 2040. Le diabète de type 1 (DT1) se caractérise par une destruction progressive des cellules β (BCM) du pancréas par une réaction auto-immune. La BCM est alors réduite à 10-50 % au moment du diagnostic, puis…, Diabetes could affect up to 642 million people worldwide by 2040. Type 1 diabetes (T1D) is characterized by the progressive destruction of pancreatic β cells (PBCs) by an autoimmune reaction. PBCs are reduced to 10-50% at the time of diagnosis and continue to decline thereafter. In type 2 diabetes…

GaN Schottky Diodes Parameter Extraction Model from S-Parameters Measurement

Beatriz Orfao, Mohammed Zaknoune, Malek Zegaoui, Javier Mateos, Tomás González, Etienne Okada, Sylvie Lepilliet, Guillaume Ducournau, Yannick Roelens, Mahmoud ABOU DAHER

GaN-on-sapphire Schottky barrier diodes (SBDs) have been fabricated for frequency multiplier applications. A complete set of characterization has been done, including DC and RF measurements. A model to extract the Schottky parameters from S-parameters measurements in small diodes is proposed,…

La spectroscopie térahertz : analyses structurales et de conduction

Romain Peretti

La gamme TéraHertz (THz) se situe entre l'électronique et la photonique. Les fréquences THz sont trop élevées pour le bon fonctionnement des transistors et trop faibles en énergie pour rendre les transitions laser efficaces. Ainsi, la gamme THz représente l'une des dernières frontières de…

Nonlinear Modeling of CMOS Compatible SiN/AlN/GaN MIS-HEMT on 200mm Si Operating at mm-Wave Frequencies

Y. Fouzi, E. Morvan, Y. Gobil, F. Morisot, Etienne Okada, S. Bollaert, N. Defrance

The performance of a CMOS-compatible SiN/AlN/GaN MIS-HEMT on 200mm Silicon substrate with high power capabilities in Ka band is evaluated. The devices show an F t /F max of 80/170 GHz for 2x50x0.15 µm 2 topology, along with outstanding and competitive large signal performance compared to GaN/SiC at…
