A model for the operation mechanism of an acoustooptic modulator (AOM) with two interdigital transducers (IDTs) is described. The 1st IDT in the AOM drives an acoustic wave on a piezoelectric substrate and the 2nd IDT controls reflection of the wave and modulation of a light intensity by controlling an electrical terminal condition at the 2nd IDT. An acoustooptic (AO) interaction is performed in a medium in contact with the substrate, using wave radiation from the substrate to the medium. An operation model of this AOM assumes the following. (1) Interference of acoustic waves in the substrate determines the characteristics of the device, where a phase of the reflection is controlled by the 2nd IDT. (2) Resonance effect inside the IDT makes the equivalent propagation length of the acoustic wave longer, which influences the frequency characteristics of the interference intensity, accompanied with an amplification of the confined wave.
