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...

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...

Terahertz near-field imaging using batch-fabricated cantilevers with 70 μm long tips

B. Walter, E. Mairiaux, D. Vignaud, Sophie Eliet, Jean-Francois Lampin, Marc Faucher

Batch-fabricated atomic force microscopy cantilevers with tip longer than 70 μm are reported. They are designed to increase terahertz focusing in scattering optical nearfield imaging. Terahertz imaging of graphene samples with sub-100 nm features is presented.

Performance analysis of 2D-OCDMA system in long-reach passive optical network

Hichem Mrabet, Iyad Dayoub, Shyqyri Haxha, Rabah Attia

In this paper, a performance analysis is reported for optical code division multiplexing (OCDM) system for long-reach passive optical network (LR-PON) systems by taking into account multiple access interference (MAI), single-mode fiber (SMF) channel effects and receiver noise. The mathematical...

Multilayer modeling of thermoacoustic sound generation for thermophone analysis and design

Pierre Guiraud, Stefano Giordano, Olivier Bou Matar, Philippe Pernod, Raphael Lardat

A general model for thermoacoustic sound generation, based on the classical conservation laws of mass, momentum and energy, is presented and adopted to analyze different thermophone structures. This model is able to describe an arbitrary multilayered (or laminated) system composed of both solid and...

Improvement in carrier dynamics in In_xGa_1-xN/GaN multi-quantum well for solar cell applications

Abdelkader Aissat, Jean-Pierre Vilcot

In this work, we have studied and simulated nanostructures to improve the solar cell efficiency. The idea of this study is to insert multi-quantum wells in the structure of a solar cell (MQWSC). The electric field, recombination, and the photogeneration rates of charge carriers in QWSC influence...

Magnetic Interactions on Oxide Ferromagnet/Ferromagnetic Intermetallide Interface

G. Ovsyannikov, V. Demidov, T. Shaikhulov, A. Klimov, Nicolas Tiercelin, Philippe Pernod, S. Nikitov

The magnetic properties of heterostructures consisting of two films are studied. The upper layer involves rare-earth intermetallic nanostructured superlattices consisting of exchange-coupled layers (TbCo 2 /FeCo) n (TCFC), and the lower layer includes either epitaxial manganite La 0.7 Sr 0.3 MnO 3...
