Abstract:
An optical pumping device is provided in which a multi-core fiber obtained by bundling up a plurality of optical fibers, which are input ports, and a double clad fiber for optical pumping are spliced through a bridge fiber composed of a double clad fiber having a tapered shape. Accordingly, it is possible to efficiently couple signal light and pumping light to the double clad fiber for optical pumping.
