The authors demonstrate the inscription of several Bragg gratings at the same location of a photosensitive fiber. This superimposed Bragg grating was fabricated by two-beam interference method using UV laser light. Effects due to the inscription of m

Cylindrical convex lenses are commonly used in fabricating fiber Bragg gratings (FBGs) by the phase mask method to increase the energy fluence of UV laser light and thereby enhance FBG productivity. We have found that lens aberrations can affect the

Long-period fiber Bragg gratings fabricated by exposure of hydrogen-loaded fiber to UV laser light exhibit large-scale dynamic evolution for approximately two weeks at room temperature. During this time two distinct features show up in their spectrum
