T. Hearne, Marie-Hélène Mammez, Dominique Mammez, M.-A. Martin-Durel, S. Eliet, Stefano Barbieri, Francis Hindle, P. Roy, Jean-Francois Lampin, Gaël Mouret, Olivier Pirali

Our team exploits the synchrotron radiation extracted by the AILES beamline of SOLEIL synchrotron facility to study different molecular physics problematics in the far-IR and THz spectral ranges. The existing experimental configuration of the beamline, with a high-resolution Bruker interferometer,…

Non-linear impairments of 300 GHz MPAs for THz communications

Laurenz John, Dominik Wrana, Benjamin Schoch, Arnulf Leuther, Pascal Szriftgiser, Guillaume Ducournau

In this paper we report on the use of THz photonics techniques to evaluate the impairments induced by non-linear behavior of 300 GHz amplifier blocks. Using a referenced THz photonics IQ generator, the error-vector magnitude evolution is analyzed towards optimum power operation point of the…

Spintronic inverse spin hall photomixing: demonstration of THz CW and frequency comb generation

Pierre Kolejak, Geoffrey Lezier, Samir Kassi, Leo Dhevarhidjian, Marie-Aline Martin-Drumel, Olivier Pirali, Guillaume Ducournau, Jean-Francois Lampin, Nicolas Tiercelin, Mathias Vanwolleghem

We demonstrate for the first time a novel THz photomixing paradigm exploiting ultrabroadband inverse spin Hall emitters. Both narrow band (∼20 Hz) CW emission by beating of two stabilized IR DFB lasers on a Pt/CoFeB/W stack is obtained as well as successful spintronic downconversion of a IR…

Optoelectronic THz mixer based on iron-doped InGaAs in a plasmonic microcavity

C. Tannoury, V. Merupo, Vanessa Avramovic, R. Kohlhaas, Guillaume Ducournau, B. Globisch, Emilien Peytavit

We present an optoelectronic THz mixer based on irondoped InGaAs integrated into a plasmonic microcavity. The measured conversion loss is as low as ∼30 dB at 300 GHz, which constitutes a 30 dB improvement in comparison to state-of-the-art photoconductors without a plasmonic microcavity. In…

Highly Efficient Terahertz Spintronic Emitter Integrated with Optimized Photonic Crystal

Pierre Kolejak, Geoffrey Lezier, Lukas Halagacka, Zuzana Gelnarova, Jean-Francois Lampin, Nicolas Tiercelin, Mathias Vanwolleghem, Kamil Postava

Spintronic terahertz emitters are new to the terahertz source family. They are broad-spectrum and gapless unlike traditional sources involving semiconductors and nonlinear crystals. Moreover, they can emit intense electromagnetic fields strong enough for nonlinear terahertz application, but on the…

Foreground Static Error Calibration for Current Sources Using Backgate Body Biasing

Clément Beauquier, Duperray David, Chadi Jabbour, Patricia Desgreys, Antoine Frappé, Andreas Kaiser

This work presents a detection and calibration circuit for current sources static mismatch introduced by the process of fabrication. The current is corrected through backgate body bias voltage control, which has the benefit of reduced additional parasitic elements, compared to more classic…

Silicon nitride drum resonator for phonon-cavity electromechanics

Xin Zhou

Silicon nitride (SiN) mechanical resonators are attractive for sensing and signal processing because of their nanogram effective mass and high-quality factor, with a typical resonance frequency in the MHz range. Up to now, SiN electromechanical resonators are based on double-clamped beam structures…
