Terahertz

Terahertz

The objective of the TERA (Nanoelectronics) group is to investigate Terahertz technologies and systems by 2025-30. To this end, the group is investing in the deployment of new experimental techniques for multi-physics characterization, new methodologies for describing components, sources and systems for terahertz applications. Terahertz radiation has excellent potential to help the understanding of fundamental and exciting new challenges at the interface between physics, optics , electronics and the life sciences but it is remained largely unexplored.

This light radiation located in this range of the electromagnetic spectrum was very difficult to generate until quite recently. Since the 1990s new developments in semiconductor physics and femtosecond laser technology have made it possible to provide light at terahertz frequencies.

The main themes developed within the TERA group are:

THz-Photonics:

Presentation of the nanoelectronics research theme

The research of the Tera group concerns components for “terahertz” (HBT SiGe and III-V, FET, Diodes) and terahertz systems such as sources, detectors, mixers, imagers. The key themes are:

Electro-optical characterization, microwave characterization and compact modelling.

  • Development of high frequency measurement methodology (on wafer S parameter measurement up to 750 GHz )
  • Very high frequency and electro-thermal modelling of SiGe HBTs

The use of “Terahertz” spectrometers cleverly completes these means of analysis,

The development of new sources (ONL, Radar, Integrated Silicon),

THz Spectroscopy and imaging.

Résumé en français

L’objectif du groupe TERA est d’étudier les technologies et les systèmes Terahertz d’ici 2025-30. Pour ce faire, le groupe investit dans le déploiement de nouvelles techniques expérimentales de caractérisation multi-physique, de nouvelles méthodologies de description de composants, de sources et de systèmes pour des applications térahertz. Le rayonnement térahertz a un excellent potentiel pour aider à la compréhension de nouveaux défis fondamentaux et passionnants à l’interface entre la physique, l’optique, l’électronique et les sciences de la vie, mais il est encore largement inexploré. La lumière située dans cette gamme du spectre électromagnétique était très difficile à générer jusqu’à tout récemment. Depuis les années 1990, de nouveaux développements en physique des semi-conducteurs et en technologie laser femtoseconde ont permis de fournir de la lumière à des fréquences térahertz.

Les thématiques développées au sein du groupe TERA sont :

THz-Photonique :

Électronique THz
