Broadband terahertz heterodyne spectrometer exploiting synchrotron radiation at sub-megahertz resolution

O. Pirali, Z. Buchanan, Sophie Eliet, M.-A. Martin-Mel, J. Turut, Francis Hindle, P. Roy, Jean-Francois Lampin, Gaël Mouret

A new spectrometer on the AILES beamline of the SOLEIL synchrotron facility to achieve sub-MHz resolution in the THz and far-IR regions is currently being developed. Thanks to a dedicated heterodyne detection by use of a new kind of molecular laser as local oscillator along with a Fast Fourier…

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…

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-…

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…

Modified AFM-tip for Infrared and THz near field microscopy

Tahsin Akalin

Near field microscopy is commonly achieved thanks to the exaltation of the field between a tip and the sample. The free space electromagnetic wave at infrared or THz frequencies is focused in this extremely small area compared to the wavelength. In many cases, the probe is a classical AFM-tip which…
