Abstract

We placed silica optical fibers into hydrogen environments of up to 30,000 psi (2,041 atm) and characterized their photosensitivity and UV-induced optical loss. We detail the relationship between the hydrogen content in the fiber and the UV-induced index change for a delivered radiation dose. We also observed high UV-induced optical loss (greater than 30 dB/cm) in these fibers and studied the cause of this loss.
