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…

Frequency noise and phase-locking of a quantum cascade laser-pumped, 1.073THz molecular laser using a 1560nm frequency comb

S Barbieri, Jean-Francois Lampin, A. Pagies, G. Santarelli, J. Hesler, W. Hansel, R. Holzwarth

Abstract: We report the measurement of the frequency noise power spectral density (PSD) of a THz molecular laser (ML) pumped by a mid-infrared (MIR) quantum cascade laser (QCL). This is obtained by beating the ML frequency with the harmonic of the repetition rate of a 1560nm frequency comb (FC). We…

The Gouy phase shift in terahertz time-domain spectroscopy and its experimental estimation, modelling and compensation

Pierre Kolejak, Kamil Postava, Martin Micica, Mathias Vanwolleghem, Jaromir Pistora

Spatial properties of pulsed beams become more important in the terahertz range, which causes that reference and sample measurements can differ in the spectral dependent complex phase called the Gouy phase. It originates from propagation of the beam wavefront close to the focus. In such a case, the…

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-…
