Double acousto-optic deflector system for increased scanning range of laser beams

Jean-Claude Kastelik, Samuel Dupont, Konstantin B. Yushkov, Vladimir Molchanov, Joseph Gazalet

A new laser scanning system is presented based on two wide-band acousto-optic deflectors. The interaction medium is tellurium dioxide. Anisotropic interactions take place under two different tangential phase matching configurations in such a way that the acousto-optic bandwidths add up. We…

High efficiency UTC photodiode for high spectral efficiency THz links

Philipp Latzel, Fabio Pavanello, Sara Bretin, Maximilien Billet, Emilien Peytavit, Christophe Coinon, X. Wallart, Jean-Francois Lampin, Mohammed Zaknoune, Guillaume Ducournau

This paper presents high-efficiency Unitravelling carrier photodiodes for THz communications. Using high-level modulation schemes, QAM-16 and 32 Gbit/s data-rate is obtained using these devices, that combine high power level and linear behavior, mandatory for high-spectral efficiency data links in…

Tunable electrical Bragg band gaps in piezoelectric plates

Charles Croënne, Clement Vasseur, Jerome O. Vasseur, Bertrand Dubus, Claude Prevot, Mai Pham Thi, Anne-Christine Hladky

In this paper, a piezoelectric plate poled along its thickness is considered. A periodic grating of electrodes is deposited on its top and bottom surfaces. An analytical model is developed considering wave propagation along the length of the plate. The device exhibits an electrical Bragg band gap…

Optimization of the second order autoregressive model AR(2) for Rayleigh-Jakes flat fading channel estimation with Kalman filter

Ali Houssam El Husseini, Eric Pierre Simon, Laurent Ros

This paper deals with the estimation of the flat fading Rayleigh channel with Jakes' Doppler spectrum (model due to R.H. Clarke in 1968) and slow fading variations. A common method in literature consists in approximating the variations of the channel using an auto-regressive model of order p (…
