Abstract

Apparatuses, systems, and methods are disclosed that incorporate Bragg gratings. Optical components and systems of the present invention include Bragg gratings produced by selectively hydrogenating one or more selected sections of an optical waveguide in general, and particularly optical fiber. Selective hydrogenation can be performed by selectively establishing local conditions in a first environment conducive to introducing greater quantities of hydrogen into selected sections than into non-selected sections, which are maintained in a second environment. The extent of selective hydrogenation and the hydrogen concentration difference between selected and non-selected section of the waveguide is a function of the temperature, pressure, and time of exposure established in the first and second environments.
