Strong Optical-Mechanical Coupling in a Vertical GaAs/AlAs Microcavity for Subterahertz Phonons and Near-Infrared Light
(American Physical Society, 2013-01)
We show that distributed Bragg reflector GaAs/AlAs vertical cavities designed to confine photons are automatically optimal to confine phonons of the same wavelength, strongly enhancing their interaction. We study the ...
Nanophononic thin-film filters and mirrors studied by picosecond ultrasonics
(American Institute of Physics, 2010-02)
Optimized acoustic phonon thin-film filters are studied by picosecond ultrasonics. A broadband mirror and a color filter based on aperiodic multilayers were optimized to work in the subterahertz range, and grown by molecular ...
Mesoporous Thin Films for Acoustic Devices in the Gigahertz Range
(American Chemical Society, 2020-06)
The coherent manipulation of acoustic waves on the nanoscale usually requires multilayers with thicknesses and interface roughness defined down to the atomic monolayer. This results in expensive devices with predetermined ...
Confinement of gigahertz sound and light in Tamm plasmon resonators
(American Physical Society, 2015-10-15)
We demonstrate theoretically and by pump-probe picosecond acoustics experiments the simultaneous confinement of light and gigahertz sound in Tamm plasmon resonators, formed by depositing a thin layer of Au onto a GaAs/AlGaAs ...
Acoustic waves from mechanical impulses due to fluorescence resonant energy (Förster) transfer: Blowing a whistle with light

Slow light and slow acoustic phonons in optophononic resonators
(American Physical Society, 2016-11-15)
Slow and confined light have been exploited in optoelectronics to enhance light-matter interactions. Here we describe the GaAs/AlAs semiconductor microcavity as a device that, depending on the excitation conditions, either ...
