Abstract
Here we report on the inscription of fiber Bragg gratings with two beam interferometry and deep ultraviolet femtosecond laser exposure. This allows to target first order Bragg grating reflections from 2000 nm down to 660 nm without the need for germanium doping or hydrogen loading. The grating in the visible region is remarkable because it bases on a femtosecond laser induced structural size around 110 nm.
