Generation of mW level in the 300-GHz band using resonant-cavity-enhanced unitraveling carrier photodiodes

Philipp Latzel, Fabio Pavanello, Maximilien Billet, Sara Bretin, Alexandre Beck, Mathias Vanwolleghem, Christophe Coinon, Xavier Wallart, Emilien Peytavit, Guillaume Ducournau, Mohammed Zaknoune, Jean-Francois Lampin

We present a resonant-cavity-enhanced broadband unitraveling carrier photodiode optimized for terahertz (THz) generation. It uses a novel semitransparent top-contact utilizing subwavelength apertures for enhanced optical transmission. The contact allows front-side illumination of the photodiode…

Study of the positioning of wireless sensors for communication at 2.4 GHz inside the train

Ulrich Biaou, Sara Iben Jellal, Michael Bocquet, S. Baranowski, Atika Rivenq, Philippe Mariage

The benefits of wireless sensor networks (WSN) offer many possibilities for the management of energy systems, which are actually based on wired systems. The need of new services on-board the train and of cables lengths reduction promote the use of wireless sensor networks in trains. Then,…
