Impact of III-nitride/Si interface preconditioning on breakdown voltage in GaN-on-silicon HEMT

Abdelkrim Khediri, Abbasia Talbi, Abdelatif Jaouad, Hassan Maher, Ali Soltani

In this paper, an AIGaN/GaN metal-oxide-semiconductor high-electron-mobility transistor (MOS-HEMT) device is realized. The device shows normal ON characteristics with a maximum current of 570 mA/mm at a gate-to-source voltage of 3 V, an on-state resistance of 7.3 Ω·mm and breakdown voltage of 500 V…

Millimeter-long travelling wave photoconductors for THz generation by photomixing

Fuanki Bavedila, Charbel Tannoury, Quyang Lin, Sylvie Lepilliet, Vanessa Avramovic, Etienne Okada, Dmitri Yarekha, Marc Faucher, David Troadec, Jean-Francois Lampin, Guillaume Ducournau, Goulc'Hen Loas, Vincent Magnin, Emilien Peytavit

In this communication we present the development of a travelling wave photoconductor for THz generation by photomixing. It is based on a silicon nitride optical waveguide coupled to a membrane-supported low-temperature-grown GaAs photoconductor embedded in a coplanar waveguide. The frequency…

Super resolution of A 400 MHz rotational line doublet with a TDS using a 850 ps long delay line

Sophie Eliet, Arnaud Cuisset, Francis Hindle, Jean-Francois Lampin, Romain Peretti

We improved the spectral resolution of THz time domain spectroscopy beyond the limit given by the delay line length. The constraint reconstruction algorithm used successfully depicted the 1.21 THz NH 3 doublet separated by ~400MHz in experimental data despite the 1.2 GHz delay line limitation.

Experimental Investigation on the Bias and Temperature Dependence of the Forward Transmission Coefficient for HEMT Technologies

Mohammad Abdul Alim, Christophe Gaquière, Giovanni Crupi

The goal of this research is to look at the effects of temperature on the forward transmission coefficient (S 21 ) of high electron-mobility transistors (HEMTs), employing various technologies. The analysis is carried out on six different devices under different bias conditions with the ambient…

A Survey of Applied Machine Learning Techniques for Optical OFDM based Networks

Hichem Mrabet, Elias Giaccoumidis, Iyad Dayoub

In this survey, we analyze the newest machine learning (ML) techniques for optical orthogonal frequency division multiplexing (O-OFDM)-based optical communications. ML has been proposed to mitigate channel and transceiver imperfections. For instance, ML can improve the signal quality under low…

Toward nanocrystal-based active nanophotonic device

Tung Dang Huu, Angela Vasanelli, Yanko Todorov, Carlo Sirtori, Yoann Prado, Christophe Delerue, Emmanuel Lhuillier

One of the great interests for colloidal nanocrystals (NCs) is their optical tunability controlled by the synthesis processes. Nonetheless, for NC-based devices, post-fabrication tunability remains very limited.1 Here, we show a NC-based active photonic device where the optical tunability is…

Heuristic approach to take up the challenge of terahertz time-domain spectroscopy for biology, Approche heuristique pour relever les défis de la spectroscopie terahertz dans le domaine temporel pour la biologie

Melanie Lavancier

There is growing interest for the terahertz (THz) frequency domain because of its particular properties. Because it is located at high frequencies for electronics, there are applications for faster data bit rate in telecommunications. Moreover, due to the low energy of the photons, there are also…, Le domaine TeraHertz (THz) est de plus en plus attractif grâce à ses propriétés particulières. Il se situe à la limite haute des fréquences pour l'électronique, ce qui crée de nombreuses applications pour les télécommunications. De plus, de par la faible énergie du photon THz, il y a des…
