A 1D Optomechanical crystal with a complete phononic band gap
J. Gomis-Bresco, D. Navarro-Urrios, M. Oudich +9
Recent years have witnessed the boom of cavity optomechanics, which exploits the confinement and coupling of optical and mechanical waves at the nanoscale. Amongst their physical i…

Phonons in Slow Motion: Dispersion Relations in Ultra-Thin Si Membranes
John Cuffe, Emigdio Chavez, Andrey Shchepetov +11
We report the changes in dispersion relations of hypersonic acoustic phonons in free-standing silicon membranes as thin as \sim 8 nm. We observe a reduction of the phase and group…

Lifetimes of Confined Acoustic Phonons in Ultra-Thin Silicon Membranes
J. Cuffe, O. Ristow, E. Chávez +8
We study the relaxation of coherent acoustic phonon modes with frequencies up to 500 GHz in ultra-thin free-standing silicon membranes. Using an ultrafast pump-probe technique of a…
