Abstract
Tunable photonic crystals that are based on acousto-optic effects were proposed in this paper. Theoretical analysis and numerical simulations were carried out for the tunable photonic crystals. According to the acousto-optic effect, acoustic waves propagating in elastic media induce periodic dielectric structures in the media, and thus the media can be used as photonic crystals. Such photonic crystals possess a prominent characteristic that the photonic band gaps can be changed real-timely by adjusting the acoustic intensity and frequency. The work done in this paper opens up a possibility to achieve tunable photonic crystals on the basis of acousto-optic effects.
