ABSTRACT
Numerical calculations are employed to study the modulation of light by surface acoustic waves (SAWs) in photonic band gap (PBG) structures. The on/off contrast ratio in a PBG switch based on an optical cavity is determined as a function of the SAW-induced dielectric modulation. We show that these structures exhibit high-contrast ratios even for moderate acousto-optic coupling. © 2003 American Institute of Physics.
