Dynamics of confined acoustic phonon modes in nanocrystalline silicon membranes
Tiago E. C. Magalhães, Tânia M. Ribeiro, Oili M. E. Ylivaara +2
We report femtosecond time-resolved measurements of confined acoustic phonons in free-standing nanocrystalline silicon membranes and compare them with the crystalline silicon count…
A self-stabilized coherent phonon source driven by optical forces
Daniel Navarro-Urrios, Nestor E. Capuj, Jordi Gomis-Bresco +5
Optical forces can set tiny objects into states of coherent mechanical oscillation, also known as mechanical or phonon lasing. We present a novel pumping mechanism in an opto-mecha…
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…
