Abstract: Systems and methods for optical computation and acousto-optic modulation are described. The systems and methods comprise acousto-optic modulators with reflectors and transducers used for actuation and modulation of mechanical waves. The systems further comprise multilayer optical computing systems incorporating arrays of acousto-optic modulators. In an embodiment, the acousto-optic modulator comprises a substrate; an optical layer coupled to a first portion of the substrate, the optical layer comprising: a free-standing portion shaped and positioned to define a gap between the free-standing portion of the optical layer and the substrate; and a rib waveguide comprising a photonic crystal, formed in the free-standing portion; and a piezoelectric transducer mechanically coupled to the free-standing portion, wherein the piezoelectric transducer comprises a piezoelectric material and a plurality of conductive electrodes disposed in electrically conductive contact with the piezoelectric material, the plurality of conductive electrodes extending from a base portion of the piezoelectric transducer.
