Abstract
Fiber Bragg grating inscription with deep ultraviolet femtosecond exposure and two beam interference is a promising technology to achieve first order fiber Bragg gratings in materials which do not show photosensitivity at conventional FBG inscription technology. It allows bypass the hydrogen loading process, which facilitates the FBG inscription process in microstructured fibers and fibers with large outer diameters. Fiber Bragg gratings in suspended core fibers and rare earth doped fibers are demonstrated.
