Computational and Theoretical Modeling of Acoustoelectrically Enhanced Brillouin Optomechanical Interactions in Piezoelectric Semiconductors

Storey, Matthew J.; Otterstrom, Nils T.; Behunin, Ryan O.; Hackett, Lisa A.; Rakich, Peter T.; Eichenfield, Matthew S.

We computationally explore the optical and elastic modes necessary for acoustoelectrically enhanced Brillouin interactions. The large simulated piezoelectric (k2 ≈ 6%) and optome-chanical (|g0| ≈ 8000 (rad/s)√m) coupling theoretically predicts a performance enhancement of several orders of magnitude in Brillouin-based photonic technologies.
