Research output: Contribution to journalArticlepeer-review


We study theoretically optomechanical interactions in a semiconductor microcavity with an embedded quantum well under optical pumping by a Bessel beam, carrying a nonzero orbital momentum. Due to the transfer of orbital momentum from light to phonons, the microcavity can act as an acoustic circulator: It rotates the propagation direction of the incident phonon by a certain angle clockwise or anticlockwise. Due to the optomechanical heating and cooling effects, the circulator can also function as an acoustic laser emitting sound with nonzero angular momentum. Our calculations demonstrate the potential of semiconductor microcavities for compact integrable optomechanical devices.
