1. A method for making an acousto-optical device, comprising:
depositing an insulating layer on a substrate;
forming a waveguiding member on the insulating layer;
depositing a membrane layer on the insulating layer and on the waveguiding member such that the deposited membrane layer abuts and overlies the waveguiding member;
removing such of the membrane layer as overlies the waveguiding member;
patterning the membrane layer so as to define therein at least one longitudinally extensive phononic resonator traversed by the waveguiding member; and
removing at least a portion of the insulating layer that underlies the membrane layer, including such portion as underlies the longitudinally extensive phononic resonator or resonators.
