<p>An optical fiber device includes a first optical element for transmitting light. An output fiber includes an output fiber core having a light receiving end optically aligned to receive light from the first optical element, and includes at least a first outer cladding on a clad portion. The output fiber includes a mode stripper adhesive with a first adhesive composition and a structural adhesive with a second adhesive composition thereon. The mode stripper adhesive is positioned closer to the first optical element than the structural adhesive to strip a majority of power of cladding guided mode(s) light before reaching the structural adhesive. The mode stripper adhesive has a lower hardness as compared to the structural adhesive, and is substantially indexed matched to an outermost layer of the output fiber that it is in direct contact with.</p> |
