Patent ID: 6931752

Claim:
A mechanism for aligning a waveguide type optical member and fiber arrays, in which the fiber arrays are moved relatively to the waveguide type optical member held at a predetermined position for alignment by means of stage mechanisms, comprising: a first stage capable of moving in a first direction (Z direction) corresponding to a direction in which the corresponding fiber array advances to and retreats from the waveguide type optical member, a holding section sustaining member for sustaining a holding section of the fiber array, a second stage provided between the first stage and the holding section sustaining member and capable of moving in a second direction (Y direction) perpendicular to the direction in which the fiber array is spread, a first angle adjusting mechanism provided between the first stage and the second stage, said first angle adjusting mechanism capable of rotating around a third direction (X direction), perpendicular to both the first direction (Z direction), and the second direction (Y direction) as the rotation axis, said first angle adjusting mechanisms having: a first member having a cylindrically concave face; a movable second member having a cylindrically convex face corresponding to the cylindrically concave face and abutting the cylindrically concave face, and a positioning and fixing means provided between the first and second members for immovably fixing the second member at a predetermined angle; and a second angle adjusting mechanism provided between the holding section sustaining member and the second stage, said second angle adjusting mechanism capable of rotating around the third direction (X direction), perpendicular to both the first direction (Z direction), and the second direction (Y direction), said second angle adjusting mechanism having: a first member having a cylindrically concave face; a movable second member having a cylindrically convex face corresponding to the cylindrically concave face and abutting the cylindrically concave face, and a positioning and fixing means provided between the first and second members for immovably fixing the second member at a predetermined angle.
