LT-GaAs-based photomixers with >2 mW peak output power up to 320 GHz

F Bavedila, Etienne Okada, Jean-Francois Lampin, Guillaume Ducournau, Emilien Peytavit

It is shown in this communication that a LT-GaAs photomixer based on an optically resonant cavity is able to generate peak output powers above 2 mW up to 320 GHz when it is driven by optical pulses of 5 ns width at a repetition rate of 10 MHz.

Terahertz pulsed-field magneto-spectrometer at room-temperature

Jean-Francois Lampin, Antoine Pagies, S Barbieri, L. Desplanque, Xavier Wallart, Jeffrey Hesler, Oleksiy Drachenko, Jean Léotin

We have developed a compact pulsed-field THz magneto-spectrometer based on a THz molecular laser and heterodyne detection both at room-temperature. The recently developed continuous-wave THz laser uses mid-IR-pumped ammonia as active medium. The receiver is based on a subharmonic mixer pumped by a…

Linearity and robustness evaluation of 150-nm AlN/GaN HEMTs

Mehdi Rzin, Matteo Meneghini, Fabiana Rampazzo, V. Gao Zhan, Carlo de Santi, Riad Kabouche, Malek Zegaoui, F Medjdoub, Gaudenzio Meneghesso, Enrico Zanoni

We report on linearity and robustness of AlN/GaN HEMTs with ultra-thin 4 nm AlN barrier for millimeter wave range applications. Static and dynamic I-V characteristics feature high peak transconductance (g mpeak) of 385 mS/mm, and the transconductance exhibits small changes with gate bias. Semi on-…

Towards broadband THz spectroscopy and analysis of sub-wavelength-size biological samples

Sergey Mitryukovskiy, Melanie Lavancier, Flavie Braud, Yue Bai, Emmanuel Dubois, Jean-Francois Lampin, Romain Peretti

We report on our recent progress toward bio-photonic applications of terahertz time-domain spectroscopy. First, we developed a technique for the confinement of broadband terahertz pulses to a sub-wavelength-volume, and will present its applications to study biological samples. Second, we will…

Optically-Pumped Terahertz Sources and Applications

S Barbieri, Joan Turut, Antoine Pagies, Jean-Francois Lampin

Abstract: Despite several progress generation of electromagnetic power in the THz range is still underdeveloped compared to the other frequency bands. Direct THz generation poses fundamental and practical problems very difficult to solve. Generating THz using sources from lower or higher…

Retrieving permittivity model parameters for polar liquids and multilayer systems through THz-TDS time-trace data analysis

Melanie Lavancier, Sergey Mitryukovskiy, Nabil Vindas, Jean-Francois Lampin, Romain Peretti

We present new features of the Fit@TDS software for the analysis of polar liquids and multilayer systems. We also show that the modeling of the absorption coefficient of polar liquids can be improved around 2 THz. Hence, this software will enable us to retrieve the parameters of the models…
