The content of discipline "Fiber Bragg gratings" covers theoretical and technological basics of creating of fiber Bragg gratings (FBG) in photorefractive optical fibers.Due to the course students will learn different methods of writing FBG, different schemes which gives ability to change refractive index in Ge-Si glasses using UV emission. Students will learn how to improve photorefractivity of optical fibers and will get knowledges about using FBG in communication technologies and sensors.
