Electrically driven exciton-polariton optomechanics at super high frequencies
Alexander S. Kuznetsov, Diego H. O. Machado, Klaus Biermann +1
Polaritons enable the resonant coupling of excitons and photons to vibrations in the application-relevant super high frequency (SHF, 3-30 GHz) domain. We introduce a novel platform…

Generation and propagation of super-high-frequency bulk acoustic wave in GaAs
Diego H. O. Machado, Antonio Crespo-Poveda, Alexander S. Kuznetsov +3
Coherent super-high-frequency (SHF) vibrations provide an excellent tool for the modulation and control of excitations in semiconductors. Here, we investigate the piezoelectric gen…
