Abstract:
1. An optical device comprising: a photodetector; a substrate having one or more V-shaped grooves defined therein; an optical fiber array having one or more optical fibers, said optical fiber array being fixed within the V-shaped grooves in said substrate by a fixing adhesive, and having an end face that performs a dividing function for dividing signal light propagated through the optical fiber array; wherein at least a first area in which said fixing adhesive is present and a second area corresponding to an opening defined by a hold down jig in which said fixing adhesive is not present, are present on said optical fiber array as viewed from above such that said second area is present at least within an optical path of divided light produced by said dividing function over said optical fiber array; said optical device further comprising a resin for achieving refractive index matching with at least said optical fibers, said resin being present in said second area located above said optical fiber array and on said optical path of divided light between said optical fibers and said photodetector.
