2022/07 - La bande Terahertz (THz) est considérée comme la prochaine frontière des communications sans fil. Les techniques émergentes de multiplexage des signaux THz devraient augmenter considérablement le capacité des communications THz bien au-delà d'une limite de canal unique. Dans ce travail, nous explorons la modalité de multiplexage par répartition en fréquence THz rendue possible par un multiplexeur add-drop (ADM) sur la base de guides d'ondes plasmoniques et fonctionnant à une fréquence porteuse de ~140 GHz.
Terahertz (THz) band is considered to be the next frontier in wireless communications. The emerging THz multiplexing techniques are expected to dramatically increase the information capacity of THz communications far beyond a single channel limit.

2021/09 - L'intérêt croissant pour les effets biologiques de l'exposition des tissus et des cellules au rayonnement térahertz (THz) est motivé par les progrès rapides de la biophotonique THz. Malgré l'attrait de la technologie THz pour le diagnostic médical et la thérapie, les connaissances sur les limites sécuritaires de l'exposition au THz sont encore limitées. Différents modes d'exposition aux ondes THz, y compris rayonnement continu versus pulsé, différentes puissances, nombre et durée des cycles d'exposition, sont systématiquement étudiés.

Different modes of THz exposure including continuous-wave versus pulsed radiation, various powers, and number and duration of exposure cycles, are systematically studied: Invited Review: O.P.

Due to relative transparancy of many dry dielectrics in the THz spectral range (that are otherwise opaque in the visible), as well as non-ionising nature of the THz waves, THz imaging promises many breakthrough industrial applications in non-distructive quality control, security and monitoring.
