ABSTRACT:
An aligning mechanism having stage mechanisms, each of which is composed of a first stage capable of moving in the direction in which a fiber array b advances to and retreats from a waveguide type optical member a, a holding section sustaining member2for the fiber array and a second stage5capable of moving in the direction perpendicular to the direction in which the fiber array spreads, wherein angle adjusting mechanisms6and7capable rotating around the rotation axis perpendicular to both the said directions are provided between the first and second stages and the holding section sustaining member and the second stage.One aligning unit can be used for aligning either of two fiber arrays and a waveguide type optical member respectively having orthogonally ground end faces or either of fiber arrays and a waveguide type optical member respectively having obliquely ground end faces, and also allows the angle to be easily changed in response to the angle of the end faces.
