Abstract
An apparatus and method of hermetically sealing a pump module for a double cladded fiber in a pump module. The apparatus includes a hermetic pump module for coupling light from a pump source into an optical waveguide. The hermetic pump module includes a hermetically sealed housing, wherein the hermetically sealed housing contains an all-glass double cladded fiber with an outer cladding, an inner cladding, and a core, wherein the double cladded fiber includes a v-groove that extends through the outer cladding into the inner cladding, a pump source that emits a light, and a transparent substrate, bonded to the glass outer cladding with a transparent adhesive, wherein the light passes through the transparent substrate and into the all-glass double cladded fiber and the v-groove couples the light into the all-glass double cladded fiber. Alternatively, the substrate may be eliminated and the light directly coupled into the all-glass double cladded fiber.
