Resonant acousto-optics in the terahertz range: TO-phonon polaritons driven by an ultrasonic wave [PDF]

open access: yes, 2011
The resonant acousto-optic effect is studied both analytically and numerically in the terahertz range where the transverse-optical (TO) phonons play the role of a mediator which strongly couples the ultrasound and light fields.
