Abstract
The finite element and transfer matrix methods are applied in the design of a Bragg grating acousto-optic modulator. For simulation purposes, the device is taken as a single structure, composed of the silica horn and the fiber Bragg grating. The approach allows the strain field to be completely characterized along the whole structure and leads to a better understanding of the influence of the horn dimensions on the design and performance of the modulator. Results obtained using the two methods show an excellent agreement with experimental data in similar structures of the same dimensions.
