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…

Retrieving permittivity model parameters for polar liquids and multilayer systems through THz-TDS time-trace data analysis

Melanie Lavancier, Sergey Mitryukovskiy, Nabil Vindas, Jean-Francois Lampin, Romain Peretti

We present new features of the Fit@TDS software for the analysis of polar liquids and multilayer systems. We also show that the modeling of the absorption coefficient of polar liquids can be improved around 2 THz. Hence, this software will enable us to retrieve the parameters of the models…

Millimeter-wave noise source development on SiGe BiCMOS 55-nm technology for applications up to 260 GHz

Joao Carlos Azevedo Goncalves, Haitham Ghanem, Simon Bouvot, Daniel Gloria, Sylvie Lepilliet, Guillaume Ducournau, Christophe Gaquière, Francois Danneville

This paper describes the development and characterization of a millimeter-wave (mmW) integrated noise source development on silicon technology for applications up to 260 GHz. The developed integrated noise source is based on p-n and Schottky junction in series, realized on the SiGe BiCMOS 55-nm…

Development of high-speed, patch-antenna intersubband photodetectors at 10.3μm

Q. Lin, S Barbieri, M. Hakl, S. Pirotta, R. Colombelli, W. Wan, H. Li, J. Cao, Jean-Francois Lampin, Emilien Peytavit

We present our work on the development of highspeed, GaAs-AlGaAs multi-quantum wells photodetectors at 10.3μm, based on two-dimensional arrays of patch-antenna resonators. First, the results of FDTD simulations will be presented that allowed to optimize the patch array geometry and fabricate a…

Tunable filter design for IR hyperspectral imaging

Justine Champagne, Samuel Dupont, Joseph Gazalet, Jean-Claude Kastelik

The use of wide-angle Acousto-Optic Tunable Filter (AOTF) for hyperspectral imaging is considered: the diffraction efficiency is calculated around a usual diffraction plane for two degrees of freedom (azimuthal and transverse angle). The efficiency evolution is also examined over a wide wavelength…

f max =800 GHz with 75 nm gate length and asymmetric gate recess for InGaAs/InAlAs PHEMT

M. Samnouni, Nicolas Wichmann, X. Wallart, Christophe Coinon, Sylvie Lepilliet, S. Bollaert

In This paper, we present a high maximum frequency of oscillation (fmax) and a current-gain cutoff frequency (fT) of 800 GHz and 260 GHz respectively with pseudomorphic high-electron mobility transistor (PHEMT), using a composite, InGaAs/InAs/InGaAs channel and an asymmetric gate recess. This…
