Repeatable optical waveguide interconnection including an index matching elastomeric solid layer and related methods

A repeatable optical fiber interconnection comprising:

• first and second optical fibers having respective first and second end faces, each of said first and second optical fibers comprising
• a core having a core index of refraction, and
• a cladding surrounding said core and having a cladding index of refraction less than the core index of refraction;
• and
• a first index matching elastomeric solid layer having a proximal face chemically bound to the first end face and a low-tack distal face opposite the proximal face to be repeatably optically coupled to the second end face, said first index matching elastomeric solid layer having an index of refraction matching at least the index of refraction of said core;
• said first index matching elastomeric solid layer comprising an acrylate polymer, and the low-tack distal face of said first index matching elastomeric solid layer having surface properties defining a wetted interface devoid of air pockets with said second end face when pressed thereagainst.
