Terahertz generation and power limits in In0.53Ga0.47As photomixer coupled to transverse-electromagnetic-horn antenna driven at 1.55 µm wavelengths

Juliette Mangeney, F. Meng, Djamal Gacemi, Emilien Peytavit, Jean-Francois Lampin, Tahsin Akalin

We report continuous wave generation at frequencies up to 2 THz using ion-irradiated In0.53Ga0.47As photomixers coupled to transverse-electromagnetic-horn antennae driven at 1.55 m wavelength. Output powers up to 0.1 W at 700 GHz have been achieved. The dependence of the output power on incident…

Atomistic simulation of plasticity in silicon nanowires

F. Cleri, T. Ishida, D. Collard, H. Fujita

We study the tensile deformation of polycrystalline Si nanowires by means of molecular dynamics simulations. The initial microstructure is composed by a network of nanocrystals glued together by a thin layer of amorphous material. Atomistic simulations could clearly identify liquidlike flow in the…

Droplet displacements and oscillations induced by ultrasonic surface acoustic waves : a quantitative study

Philippe Brunet, Michael Baudoin, Olivier Bou Matar, Farzam Zoueshtiagh

We present an experimental study of a droplet interacting with an ultrasonic surface acoustic wave. Depending on the amplitude of the wave, the drop can either experience an internal flow with its contact line pinned, or (at higher amplitude) move along the direction of the wave also with internal…

Analysis of the degradation induced by focused ion Ga3+ beam for the realization of piezoelectric nanostructures

Denis Remiens, R.H. Liang, Caroline Soyer, D. Deresmes, David Troadec, S. Quignon, Antonio Da Costa, Rachel Desfeux

Piezoelectric nanostructures (islands of dimensions in the lateral size range 50–500 nm) have been fabricated by focused Ga3+ ion beam (FIB) etching on PbZr0.54Ti0.46O3 thin films obtained by magnetron sputtering. The degradation induced by the etching process is investigated through the evolution…

Enhanced acousto-optic interactions in a one-dimensional phoxonic cavity

I. Psarobas, N. Papanikolaou, N. Stefanou, Bahram Djafari-Rouhani, Bernard Bonello, Vincent Laude

We report on the occurrence of strong nonlinear acousto-optic interactions in a one-dimensional model phoxonic cavity that supports, simultaneously, photonic and phononic localized resonant modes, by means of rigorous electrodynamic and elastodynamic calculations. We show that these interactions…

Dual phononic and photonic band gaps in a periodic array of pillars deposited on a thin plate

Y. El Hassouani, C. Li, Yan Pennec, E.H. El Boudouti, H. Larabi, Abdellatif Akjouj, Olivier Bou Matar, V. Laude, N. Papanikolaou, A. Martinez, Bahram Djafari-Rouhani

We discuss the simultaneous existence of phononic and photonic band gaps in a periodic array of holes drilled in a Si membrane. We investigate in detail both the centered square lattice and the boron nitride (BN) lattice with two atoms per unit cell which include the simple square, triangular and…

Terahertz photomixers based on ultra-wideband horn antennas, Photomélangeurs térahertz à antennes cornet ultra-large bande

Alexandre Beck, Tahsin Akalin, Guillaume Ducournau, Emilien Peytavit, Jean-Francois Lampin

We review recent advances in the development of new terahertz photomixers based on the integration of an ultrafast photodetector with an ultra-wideband transverse electromagnetic wave horn antenna. We expose first a simplified theory of this antenna, the choice of the dimensions and the results of…, Cet article expose le développement récent d'une nouvelle génération de photomélangeurs térahertz basés sur l'intégration d'un photodétecteur ultra-rapide avec une antenne ultra-large bande de type cornet à onde transverse électromagnétique. Nous exposons d'abord la théorie…
