Monomodal or weakly multimodal optical fibers, with large numerical aperture at ends, having tip(s) of transparent plastics for forming specific connections e.g. to other optical fibers or lasers

摘要

New monomodal or weakly multimodal optical fibers, with a very large numerical aperture at the ends, have at one or both ends a non-removable tip of transparent plastics, which can be used to form specific connections.
