Patent

CA 2360974

In a semiconductor pumping light source module according to the present invention, a fiber grating (FBG) is disposed, outside a ferrule, in an optical fiber that is inside a protective tube to define a cavity between the FBG and the semiconductor laser device. The FBG is disposed, outside the ferrule, in the optical fiber that is inside the protective tube inside a protective boot. The FBG is disposed on the optical fiber at a portion where no adhesive exists inside the protective tube. The semiconductor pumping light source module is used as a pumping light source of the optical amplifier. The semiconductor pumping light source is also used as the pumping light source of a Raman amplifier.
