Active chiral control of GHz acoustic whispering-gallery modes
We selectively generate chiral surface-acoustic whispering gallery modes in the gigahertz range on a microscopic disk by means of an ultrafast time-domain technique incorporating a spatial light modulator. Active chiral control is achieved by making use of an optical pump spatial profile in the form...
