摘要

The radiation response of distributed feedback (DFB) Bragg gratings written with continuous wave (CW) UV or IR femtosecond lasers in Ge-doped fibers was studied up to the total ionizing dose of 1 kGy(SiO2) since these components are aimed to be used as the laser cavity for space applications. We demonstrated that the ultranarrow passband peaks shift of the same quantity of their Bragg peak since t...
