Dose-rate dependencies in gamma-irradiated fiber Bragg grating filters

    Research outputpeer-review

    Abstract

    Wavelength-division multiplexed fiber-optic links could find applications in various radiation environments. Space industry, for example, could benefit from radiation-tolerant high-speed optical links for the next generation of observation satellites. For application in the nuclear energy industry, the use of passive optical devices also needs to be evaluated at high dose rates and total doses. Our previous results have shown that the in-fiber Bragg grating filters are key components in the radiation-resistant passive optical links, as they showed a remarkably high radiation-acceptance level in terms of total absorbed dose. The dose-rate dependencies also needed to be evaluated. We therefore gamma-irradiated fiber Bragg grating filter at several dose rates ranging from 1 to 25 kGy/h. We show, for the first time, that the dose rate does not affect the full-width at half-maximum of the Bragg peak and that the saturating Bragg peak shift remains.
