Abstract :
Irradiation of the core of an optical fiber with ultraviolet light photoinduces a permanent change in the core refractive index. This photorefractive effect called “photosensitivity” has great practical significance: it makes possible passive fiber devices that have applications in optical communications and optical sensing. In this paper we discuss two novel applications of photosensitivity, for optical fiber dispersion compensation and optical storage
