[Photomélangeurs térahertz à antennes cornet ultra-large bande]
Cet article expose le développement récent d'une nouvelle génération de photomélangeurs térahertz basés sur l'intégration d'un photodétecteur ultra-rapide avec une antenne ultra-large bande de type cornet à onde transverse électromagnétique. Nous exposons d'abord la théorie simplifiée de cette antenne puis le choix des dimensions et les résultats de simulations électromagnétiques. Nous exposons ensuite le procédé de réalisation technologique de l'antenne et son intégration avec des photodétecteurs ultra-rapides. Enfin nous présentons une expérience de photomélange et des résultats de mesures de diagrammes de rayonnement.
We review recent advances in the development of new terahertz photomixers based on the integration of an ultrafast photodetector with an ultra-wideband transverse electromagnetic wave horn antenna. We expose first a simplified theory of this antenna, the choice of the dimensions and the results of electromagnetic modeling. We expose then the technological process of the antenna and its integration with ultrafast photodetectors. In the last part we present a photomixing experiment and radiation patterns measurements.
