| Sumario: | Cavity optomechanics is a strongly active area of activity both in the domain of coherent control at the quantum level, as for the ultrasensitive displacement sensing (as for example in Ligo). In this context semiconductor hybrid devices provide a unique platform for the coupling of different fundamental excitations (electrons, phonons and photons), as for the operation at ultra-high mechanical frequencies (GHz-THz). This should allow the access to quantum phenomena at higher temperatures with larger immunity to environmental noise. This project aims to develop a platform for optomechanical coherent control based in the modulation of cavity polaritons by stimulation with optically generated phonons in the GHz-THz range and with 3D confinement in laterally microstructured planar microcavities. To access a strong coupling between phonons and polaritons we will explore both the long coherence time of polariton Bose condensates (times that can be larger than some hundreds of picoseconds), as well as the ultra-strong optomechanical coupling g0 in the presence of resonant photoelastic mechanisms. |
