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…

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…

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…

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…

Combined UTC-PD integrated on-chip THz near field microscopy with coupled planar Goubau lines

Tahsin Akalin, Abdallah Chahadih, Abbas Ghaddar, Ibrahim Tirer

In most of the cases for terahertz near field microscopy, a free space propagating electromagnetic wave interacts with a small tip placed above the sample. In our original approach, we use a guided way to bring the terahertz wave and to improve the interaction efficiency with the sample. The idea…

Conductivity of Manganite Films under the Action of Tension Caused by the Deformation of Substrate

G. Ovsyannikov, T. Shaikhulov, V. Shakhunov, A. Klimov, V. Preobrazhenskii, Nicolas Tiercelin, Philippe Pernod

The electron transport properties of strained thin La 0.7 Ba 0.3 MnO 3 (LBMO) epitaxial films are studied. Films 40-100 nm in thickness were prepared by laser ablation at a temperature T = 700-800°C in pure oxygen atmosphere of 0.3-1 mBar. Ferroelectric crystal substrates (011)0.79PbMg 1/3 Nb 2/3 O…

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…
