Abstract

In earlier work, noncollinear acousto-optic (AO) interaction has been analyzed in an acoustic metamaterial modeled by a simple dispersion relation. Here we investigate nominally collinear AO interaction in an acoustic metamaterial. We show that phase matching between the undiffracted and diffracted orders, not normally achievable in collinear conventional AO (CAO), can be satisfied using the dispersive acoustic behavior in meta-acousto-optics (MAO). We develop a theory for detailed analysis of collinear interaction between light and CW and multi-frequency (pulsed) acoustic waves in acoustic metamaterials. Application of collinear MAO to AO tunable filters is also investigated.
