Journal ArticleDOI
Pulsed laser crystallization and structuring of a-Ge on GaAs
Paulo V. Santos,Antonio Ricardo Zanatta,F. Dondeo,A. Trampert,Uwe Jahn,David Comedi,M. A. A. Pudenzi,I. Chambouleyron +7 more
TL;DR: In this paper, a line gratings of amorphous Ge (a-Ge) films on GaAs (1 0 0) substrates by nanosecond laser pulses were obtained for laser fluencies that completely melted the Ge film but not the substrate.
Journal ArticleDOI
High contrast optical modulation by surface acoustic waves
TL;DR: In this article, the on/off contrast ratio in photonic band gap (PBG) switch based on optical cavity is determined as a function of the SAW induced dielectric modulation.
Journal ArticleDOI
On-chip generation and dynamic piezo-optomechanical rotation of single photons
Dominik D. Bühler,M.R. Weiss,Antonio Crespo-Poveda,Emeline D.S. Nysten,Jonathan J. Finley,Kai Müller,Paulo V. Santos,M. M. de Lima,Hubert J. Krenner +8 more
TL;DR: In this article , a dynamically reconfigurable integrated photonic circuit comprising integrated quantum dots (QDs), a Mach-Zehnder interferometer (MZI) and surface acoustic wave transducers directly fabricated on a monolithic semiconductor platform is presented.
Journal ArticleDOI
Stern–Gerlach spin filter using surface acoustic waves
TL;DR: In this article, the authors proposed the ambipolar carrier transport by surface acoustic waves (SAWs) in a semiconductor quantum well for the realization of the Stern-Gerlach (SG) experiment in the solid phase.
Journal ArticleDOI
Carrier Transport in GaAs Nanowires Using Surface Acoustic Waves
Alberto Hernández-Mínguez,M. Möller,Carsten Pfüller,Steffen Breuer,Oliver Brandt,M. M. de Lima,Alberto García-Cristóbal,Andrés Cantarero,Lutz Geelhaar,Henning Riechert,Paulo V. Santos +10 more
TL;DR: In this paper, the authors demonstrate the high-frequency manipulation of carriers in GaAs nanowires without the use of electrical contacts, which opens new perspectives for applications in opto-electronic devices operating at GHz frequencies.
