Nanomechanical resonators based on adiabatic periodicity-breaking in a superlattice
F. R. Lamberti, M. Esmann, A. Lemaitre +7
We propose a novel acoustic cavity design where we confine a mechanical mode by adiabatically changing the acoustic properties of a GaAs/AlAs superlattice. By means of high resolut…
Acoustic Localization Phenomena in Ferroelectric Nanophononic Devices
A. Bruchhausen, N. D. Lanzillotti-Kimura, B. Jusserand +4
The engineering of phononic resonances in ferroelectric structures appears as a new knob in the design and realization of novel multifunctional devices. In this work we experimenta…
Direct measurement of coherent subterahertz acoustic phonons mean free path in GaAs
Romain Legrand, Agnès Huynh, Bernard Jusserand +2
Phonon mean free path is generally inferred from the measurement of thermal conductivity and we are still lacking precise information on this quantity. Recent advances in the field…
Polariton resonances for ultra-strong coupling cavity optomechanics in GaAs/AlAs multiple quantum wells
B. Jusserand, A. Poddubny, A. Poshakinskiy +2
Polariton-mediated light-sound interaction is investigated through resonant Brillouin experiments in GaAs/AlAs multiple-quantum wells. Photoelastic coupling enhancement at exciton-…
Dispersion and damping of multi-quantum well polaritons from resonant Brillouin scattering by folded acoustic modes
B. Jusserand, A. Fainstein, R. Ferreira +2
We report on confined exciton resonances of acoustic and folded acoustic phonon light scattering in a GaAs/AlAs multi-quantum-well. Significant variations of the line shifts and wi…
Dynamical Corrections to Spin Wave Excitations in Quantum Wells due to Coulomb Interactions and Magnetic Ions
Cynthia Aku-Leh, Florent Perez, Bernard Jusserand +2
We have measured dispersions of spin-flip waves and spin-flip single-particle excitations of a spin polarized two-dimensional electron gas in a CdMnTe quantum well using resonant R…
