Abstract: Methods and apparatus relate to optical fibers suitable for use in sensing applications exposed to radiation environments. The fibers include a core of pure silica or chlorine doped silica surrounded by a fluorinated silica cladding. These glasses for the core and cladding utilize dopants that resist radiation-induced attenuation. A two step process for forming the cladding can achieve necessary concentrations of the fluorine by performing a soot deposition process in a different environment from a consolidation process where the soot is sintered into a glass. Concentration of fluorine doped into the cladding layer enables obtaining a numerical aperture that confines a mono-mode of the fiber to resist bend-induced attenuation. Dimensions of the fiber further facilitate bending ability of the fiber.
