Exciton-resonant detection of high-frequency surface acoustic waves from subwavelength metal gratings

Olga Ken, Dmytro Horiachyi, Ilya Akimov +8

We report on all-optical generation and detection of high-frequency (up to about 30 GHz) surface acoustic waves (SAWs) in GaAs/AlGaAs heterostructures with short-period Au gratings…
