Abstract
An optical fiber combiner includes optical fiber components including a predetermined area and a refractive index portion formed on the predetermined area; a housing including a channel with the optical fiber components disposed through, fastening members for fastening the optical fiber components, and a cover for sealing the channel; and a conductive material disposed in the channel. In response to laser beams impinging on the optical fiber components, heat is generated by the refractive index portion, the heat is absorbed by the conductive material, and the heat is further transferred to the housing and the cover by thermal conduction for dissipation.
