ABSTRACT:
Optical fibers are inserted and bonded in a two dimensional array of feedthroughs provided by an insert having a top plate, a bottom plate and a sandwiched spacer plate. Top and bottom plate feature funnel shaped hole sections that capture the approaching fiber end during its insertion. The funnel sections terminate in narrow hole sections that tightly hold the inserted fiber ends. Having top and bottom plate spaced apart provides for high angular precision of the bonded fiber ends with minimal fabrication effort of the insert. Optical fibers may be combined in linear arrays and simultaneously inserted significantly reducing assembly efforts. The insert is attached to a fiber housing and hermetically sealed within an external housing, which features a glass plate to provide beam propagation to and from the fiber ends. An optical gel fills the gap between the insert's output face and the glass plate.
