METALLIC GLASS HERMETIC COATING FOR AN OPTICAL FIBER AND METHOD OF MAKING AN OPTICAL FIBER HERMETICALLY COATED WITH METALLIC GLASS

摘要

In one approach to manufacturing hermetically-coated optical fibers, a metallic glass jacket [22] is fabricated over a preform [26] having the desired core and overclad profile for the finished fiber. The jacketed preform is drawn to form the hermetically sealed optical fiber [34]. In a further embodiment of the invention, a freezing technique is used.
