“…The sensitivity of elliptical core fibers (geometrical shape birefringence) was measured at 1.3 and 1.55 under different irradiation conditions [129], [130]. Steady-state irradiation effects on PANDA fibers were described in [131], [133].…”

“…Recently, PMF with pure-silica core [138] and nitrogen [139] doped cores have been reported with enhanced radiation tolerance. Furthermore, the asymmetrical structure of a highly birefringent fiber could lead to differential RIA level between the two orthogonal polarization axes, as evidenced by Friebele et al under steady-state irradiation [129] and following a radiation pulse [140]. This might have practical implications for example in fiber-optic gyroscopes, in which the polarization axis exhibiting the lowest RIA might be preferred.…”

International audienceIn this review paper, we present radiation effects on silica-based optical fibers. We first describe the mechanisms inducing microscopic and macroscopic changes under irradiation: radiation-induced attenuation, radiation-induced emission and compaction. We then discuss the influence of various parameters related to the optical fiber, to the harsh environments and to the fiber-based applications on the amplitudes and kinetics of these changes. Then, we focus on advances obtained over the last years. We summarize the main results regarding the fiber vulnerability and hardening to radiative constraints associated with several facilities such as Megajoule class lasers, ITER, LHC, nuclear power plants or with space applications. Based on the experience gained during these projects, we suggest some of the challenges that will have to be overcome in the near future to allow a deeper integration of fibers and fiber-based sensors in radiative environments
