Reliability of silica-based planar-lightwave circuit-type 1 X 8 splitter module

Fiber-to-waveguide connection is one of the key technologies in the realization of guided-wave circuits.1 We have already developed a fiber-connection technique that uses UV-curable adhesive since it seems to be advantageous in terms of mass production and low cost.2 This paper applies the technique to 1 × 8 splitter modules and studies their reliability.
