Continuous-wave lines up to 5.5 THz from the ammonia laser pumped by a quantum cascade laser

Jean-Francois Lampin, M.-H. Mammez, Z. Buchanan, M. Micica, O. Pirali, M.-A. Martin-Drumel, Sophie Eliet, S Barbieri, Francis Hindle, P. Roy, Gaël Mouret

We have recently demonstrated a continuous wave molecular laser emission based on ammonia optically pumped by a quantum cascade laser. We report here new results obtained with an optimized laser prototype pumped by a tunable external cavity quantum cascade laser. New laser lines with high output…

Serial interference cancellation for improving uplink in LoRa-like networks

Angesom Ataklity Tesfay, Eric Pierre Simon, Guillaume Ferré, Laurent Clavier

In this paper, we present a new receiver design, which significantly improves performance in the Internet of Things networks such as LoRa, i.e., having a chirp spread spectrum modulation. The proposed receiver is able to demodulate multiple users simultaneously transmitted over the same frequency…

Power measurement setup development for on-wafer characterization at 185-191 GHz

Caroline Maye, Sylvie Lepilliet, Etienne Okada, Daniel Gloria, Guillaume Ducournau, Christophe Gaquière

This article presents off-wafer scalar power setup dedicated to load-pull measurement for characterization of on-wafer active devices between 185 and 191 GHz. The system architecture allows us to determine the absorbed input power, the output power delivered to the load, the power added efficiency…

A superheterodyne 300 GHz wireless link for ultra-fast terahertz communication systems

Iulia Dan, Guillaume Ducournau, Shintaro Hisatake, Pascal Szriftgiser, Ralf-Peter Braun, Ingmar Kallfass

A superheterodyne transmission scheme is adopted and analyzed in a 300 GHz wireless point-to-point link. This was realized using two different intermediate frequency (IF) systems. The first uses fast digital synthesis which provides an IF signal centered around a carrier frequency of 10 GHz. The…
