Abstract

The effects of gamma radiation on the cladding modes of a pure silica core fiber are investigated for the first time. The effective indices of certain cladding modes increase with accumulated dose of gamma radiation, whereas those of others decrease. By contrast, all cladding modes of standard fibers exhibit an increase in index following exposure. The distinction between sets of cladding modes in the pure silica core fiber might be due to radiation induced strain at the interface between the inner depressed cladding and the outer region of pure silica. The pure silica core fiber might provide radiation resilience in its core mode alongside sensitive dosimetry through its cladding modes.
