Abstract:
An optical device package comprising:a substrate having mounted on its one side optical devices and having formed in said one side positioning parts for defining the positions of optical axes of said optical devices, each said optical device having plural pairs of ports for externally receiving/delivering light beams on both sides thereof opposite to each other, said positioning parts being formed in plural pairs therewith, and each said positioning part in each pair being provided to correspond to each said port of each pair of each said optical device; a case with said substrate housed therein; two optical connector ferrules fitted in windows formed in two opposite sidewalls of said case; flexible optical waveguides having one ends held in optical fiber receiving holes formed in said optical two connector ferrules and extended at the other ends into said case and positioned in said positioning parts to define positions of optical axes of said flexible optical waveguides in alignment with the corresponding ports of said optical devices; and two ferrule couplers provided on end faces of said two optical connector ferrules externally exposed out of said case, for optically coupling externally connecting optical fibers held in two externally connecting optical connector ferrules to said flexible optical waveguides held by the corresponding optical connector ferrules, whereby any pair of the optical fibers held in said two externally connecting optical connector ferrules are coupled together by means of the flexible optical waveguides without adjusting offset in alignment of the axes of the pair of the optical fibers.
