Abstract

This paper presents an experimental study of the photosensitivity of various types of photosensitive optical fiber. A new interferometric technique based on low-finesse fiber Bragg grating Fabry-Perot interferometers allowed the determination of the evolution of the refractive index during exposure to ultra-violet radiation from a KrF excimer laser. It was demonstrated experimentally that enhanced photosensitivity of standard SMF-28 fiber retains after complete outdiffusion of hydrogen. The dependencies of effective refractive index change versus fluence are presented for different photosensitive fibers and hydrogen-loaded fiber.
