Cl₂/Ar based atomic layer etching of AlGaN layers

Sébastien Aroulanda, Olivier Patard, Philippe Altuntas, Nicolas Michel, Jorge Pereira, Cédric Lacam, Piero Gamarra, Sylvain L. Delage, N. Defrance, Jean-Claude de Jaeger, Christophe Gaquière

This paper reports on atomic layer etching of several III-N materials such as GaN, AlN, AlGaN, and InAlGaN based on a sequential surface modification by chlorine adsorption followed by a low energy Ar plasma exposure to remove the modified layer using a reactive ion etching system. A study on the…

New millimeter wave generation scheme for MIMO-OFDM based Radio-over-Fiber system

M. El Yahyaoui, A. El Moussati, Ghaïs El Zein, Kamel Haddadi

This paper proposes a new scheme for the generation and transmission of a MIMO-OFDM signal over optical fiber using a single local oscillator (LO) at 15 GHz. This technique is based on subcarrier multiplexing and Optical Carrier Suppression (OCS) modulation using both Dual-Parallel Mach–Zehnder…

Micro-Electro-Mechanical-Systems advances for measurements at small scales: the vertical silicon probes technology extended to nearfield optics

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

Instrumentation intending to go beyond the limits of current Atomic Force Microscope setups (AFM), and applications requiring AFM to be integrated in non-standards environmental conditions need sensors that overcome limitations given by available probes. We show that the vertical probe technology…

Second-order autoregressive model-based Kalman filter for the estimation of a slow fading channel described by the Clarke model: Optimal tuning and interpretation

Ali Houssam El Husseini, Eric Pierre Simon, Laurent Ros

This paper treats the estimation of a flat fading Rayleigh channel with Jakes' Doppler spectrum model and slow fading variations. A common method is to use a Kalman filter (KF) based on an auto-regressive model of order p (AR(p)). The parameters of the AR model can be simply tuned by using the…
