Abstract
Optical interferometric techniques and systems for fabricating fiber Bragg gratings in photosensitive optical fibers by using an acousto-optic element to generate and control the radiation pattern with a high resolution. The radiation pattern may be programmable in that different radiation patterns may be produced by controlling the acousto-optic element.
