An interferometric scanning microwave microscope and calibration method for sub-fF microwave measurements

Thomas Dargent, Kamel Haddadi, T. Lasri, N. Clément, D. Ducatteau, Bernard Legrand, H. Tanbakuchi, Didier Theron

We report on an adjustable interferometric set-up for Scanning Microwave Microscopy. This interferometer is designed in order to combine simplicity, a relatively flexible choice of the frequency of interference used for measurements as well as the choice of impedances range where the interference…

Electron delay analysis and image charge effect in AlGaN/GaN HEMT on silicon substrate

Alain Agboton, N. Defrance, Philippe Altuntas, Vanessa Avramovic, Adrien Cutivet, Rezki Ouhachi, Jean-Claude de Jaeger, Samira Bouzid-Driad, Maher, Hassan, M. Renvoise, Peter Frijlink

A delay time analysis is carried out for SiN-passivated AlGaN/GaN High Electron Mobility Transistors (HEMTs) on silicon substrate featuring gate length of 90 nm. The influence of high parasitics in the access pads is considered using de-embedding procedure from the measured S parameters. From the…

Experimental demonstration of direct terahertz detection at room-temperature in AlGaN/GaN asymmetric nanochannels

Paul Sangare, Guillaume Ducournau, Bertrand Grimbert, Virginie Brandli, Marc Faucher, Christophe Gaquière, Ana Iniguez-De-La-Torre, Ignacio Íñiguez-De-La-Torre, Jean-Francois Millithaler, Javier Mateos, Tomás González

The potentialities of AlGaN/GaN nanodevices as THz detectors are analyzed. Nanochannels with broken symmetry (so called self switching diodes) have been fabricated for the first time in this material system using both recess-etching and ion implantation technologies. The responsivities of both…

A fully distributed non linear waveguide using (Pb,Sr)TiO3 thin film : second and third harmonics generation

Freddy Ponchel, Ludovic Burgnies, D. Ducatteau, Eric Lheurette, Denis Remiens, D. Lippens

We report on the experimental investigation of a non-linear (NL) Co-Planar Waveguide (CPW) fabricated by means of a ferroelectric film. In contrast to conventional NL-CPW, periodically loaded by lumped varactors, the tunable ferroelectric material is fully distributed along the propagation…

Metamaterial-inspired bandpass filter for the terahertz Goubau line

Ali Karami Horestani, Withawat Withayachumnankul, Christophe Fumeaux, Derek Abbott, Tahsin Akalin

Recently, it has been shown that a single wire Goubau line that supports surface wave propagation can be used as an effective terahertz waveguide with low attenuation and low dispersion. In order to fully exploit Goubau lines in terahertz systems, for example for communication applications,…
