Journal ArticleDOI
Acoustically driven arrayed waveguide grating.
Antonio Crespo-Poveda,Alberto Hernández-Mínguez,Bernardo Gargallo,Klaus Biermann,Abbes Tahraoui,Paulo V. Santos,Pascual Muñoz,Andrés Cantarero,M. M. de Lima +8 more
TL;DR: It is demonstrated that compact tunable phased-array wavelength-division multiplexers driven by surface acoustic waves (SAWs) in the low GHz range can be demonstrated with good agreement between theory and experiment.
Journal ArticleDOI
Dynamic exciton-polariton macroscopic coherent phases in a tunable dot lattice
E. A. Cerda-Méndez,D. N. Krizhanovskii,Klaus Biermann,Rudolf Hey,M. S. Skolnick,Paulo V. Santos +5 more
TL;DR: In this paper, the enhancement of the nonlinear properties of exciton-polariton macroscopic coherent phases created by resonant optical excitation under the spatial modulation of a square acoustic lattice was reported.
Journal ArticleDOI
Switching of magnetic moments of nanoparticles by surface acoustic waves
Javier Tejada,Eugene M. Chudnovsky,Ricardo Zarzuela,Nahuel Statuto,J. Calvo-de la Rosa,Paulo V. Santos,Alberto Hernández-Mínguez +6 more
TL;DR: In this paper, the magnetic relaxation from a saturated state becomes significantly enhanced in the presence of the SAW at a constant temperature of the substrate, and the dependence of the relaxation on SAW power and frequency has been investigated.
Journal ArticleDOI
Optical Activity in Semiconductors: Stress and Confinement Effects
Journal ArticleDOI
Lattice Distortion Effects on the Magnetostructural Phase Transition of MnAs
Fernando Iikawa,M. J. S. P. Brasil,C. Adriano,O. D. D. Couto,Carlos Giles,Paulo V. Santos,Lutz Däweritz,Ivan Rungger,Stefano Sanvito +8 more
TL;DR: The results give direct information on the dependence of the phase-transition temperature of MnAs films on the lattice parameters, and open exciting prospects for magneto-mechanical devices, where the critical temperature for ferromagnetism can be engineered by external stress.
