Abstract:
A junction for forming a hermetic seal about an optical waveguide, said junction comprising:a tube for providing fluid communication between a first orifice and a second orifice, a cap disposed for covering the first orifice, said cap for reducing a flow of molten metal through the first orifice when the optical waveguide is disposed within the cap, said tube being sufficiently wide to support the optical waveguide disposed between the first orifice and the second orifice while simultaneously permitting molten metal at a predetermined temperature to flow within the tube, such that, in use, the optical waveguide is disposed within the tube, molten metal is provided within the tube and flows to the cap and the molten metal solidifies, thereby forming a hermetic seal between the optical waveguide and the tube.
