Innovative Packaging Integration Strategy for BiCMOS ICs Operating beyond 200 GHz

David Ovalle-Taylor, Frédéric Gianesello, Cyril Luxey, Guillaume Ducournau

In this paper, an innovative packaging integration strategy compatible with Silicon-based technologies is proposed. It is assessed beyond 200 GHz by the integration of a BiCMOS WR3 back-to-back waveguide (WG) to suspended stripline (SSL) transition in organic laminate substrate. An insertion loss…

One step forward passive baseline-free imaging using nonlinear secondary noise sources

Lynda Chehami, Marina Terzi, Emmanuel Moulin, E. Chatelet, Francesco Massi, Julien de Rosny

This paper introduces the concept of secondary noise sources for passive defect localization in structures. The proposed solution allows for the exploitation of the principle of Green's function retrieval from noise correlation, even in the absence of an adequate ambient noise. The main…

[Invited] From a single dendrite to dendritic networks: towards multi-terminal OECTs

C. Scholaert, K. Janzakova, Yannick Coffinier, Sébastien Pecqueur, F. Alibart

In the quest to change the way we envision computing, the ability to create connections in between computing nodes on demand offers the very exciting possibility to explore bottom-up strategies when it comes to thinking the design of electronic devices a nd circuits. Recently, the growth of…

RF Performance of large germanium telluride switches for power application

Ismaël Charlet, Bruno Reig, Corentin Mercier, Julien Delprato, Vincent Puyal, Clémence Héllion, Marjolaine Allain, Stéphane Monfray, Alain Fleury, Frédéric Gianesello, Philippe Cathelin, Jean-François Robillard, Emmanuel Dubois, Jose Lugo-Alvarez

This paper reports the integration and characterization of germanium telluride (GeTe) phase-change material (PCM)-based RF switches in series configuration with a 89 μm wide PCM element to address sub-6G power handling requirements. Switching conditions using indirect heating, as well as small- and…

[Invited] Pushing the breakdown voltage and temperature capabilities of GaN HEMTs by using UWBG Al-rich channel

F Medjdoub

The rapidly increasing power demand, downsizing of power electronics and material specific limitation of silicon has led to development of AlGaN/GaN heterostructures. Commercial GaN power devices are best available for radio frequency (RF) and high voltage switching applications. Emerging AlxGa1-xN…

Low-loss, 1-m long length, hollow-core THz waveguide operating at 1 THz, based on anti-resonant guiding mechanism

Georges Humbert, Jean-Louis Auguste, Guillaume Ducournau, Jean-Francois Lampin

A hollow-core THz waveguide composed of 10 silica capillaries is designed and fabricated. The waveguide based on the anti-resonant guiding mechanism presents a large transmission window (∼>600 GHz) centered at 1 THz, with measured propagation losses below 0.5 dB/m.

Spintronic Terahertz Emitter on a Fiber Tip

Felix Paries, Nicolas Tiercelin, Geoffrey Lezier, Mathias Vanwolleghem, Felix Selz, Maria-Andromachi Syskaki, Fabian Kammerbauer, Gerhard Jakob, Martin Jourdan, Mathias Kläui, Zdenek Kaspar, Tobias Kampfrath, Tom Seifert, Georg Von Freymann, Daniel Molter

Spintronic terahertz emitters have attracted considerable interest within the last decade. They promise terahertz sources with unmatched broad frequency bandwidth which are easy to manufacture and operate, and therefore easy to scale at low cost. However, the experiments and proofs of concept rely…

On-wafer RF high-power measurement with an LSMO load at 40 GHz

T. Quinten, Jean-Francois Lampin, Etienne Okada, V. Pierron, C. Gunther, Laurence Méchin, B. Walter, B. Guillet

We present a novel technique to measure RF power directly in the plane of a DUT using a CPW (CoPlanar Waveguide) test-pattern as an on-wafer power meter. Preliminary results show that we have been able to measure 24 dBm at 40 GHz.

59 Lines Measurement in a Single Experiment using Super-Resolution TDS

Noureddin Osseiran, Aditya Raj, Théo Hannotte, Sophie Eliet, Romain Peretti

Terahertz time domain spectroscopy (THz-TDS) has emerged as a versatile tool for investigating the physical properties of materials. However, its potential for gas-phase studies has remained largely unexplored, and it gained attention recently. We present here an extended application of the…
