Abstract:
1. An optical fiber device, comprising: a first optical element for transmitting light received from a light source; at least one output fiber including an output fiber core having a light receiving end optically aligned to receive said light from said first optical element, and at least a first outer cladding on a clad portion of said output fiber core; wherein said output fiber includes an adhesive containing portion securing said output fiber to a substrate including a mode stripper adhesive comprising a first adhesive composition thereon and a structural adhesive comprising a second adhesive composition thereon different from said first adhesive composition, wherein a leading edge of said mode stripper adhesive is positioned closer to said first optical element than said structural adhesive to first receive said light and strip at least a majority of power of cladding guided mode(s) of said light before reaching said structural adhesive; wherein said mode stripper adhesive has a lower hardness as compared to said structural adhesive, and wherein said mode stripper adhesive substantially indexed matched to an outermost layer of said output fiber that it is in direct physical contact with said mode stripper adhesive.
