APPARATUS FOR SEARCHING FOR THE OPTIMUM COUPLING BETWEEN AN OPTO-ELECTRONIC COMPONENT AND A SINGLE-MODE OPTICAL FIBER AND FOR THEIR ASSEMBLY IN A MODULE

摘要

P It includes a positioning bench consisting of a fixed part and a mobile part. The position of the movable part is adjustable relative to the fixed part. It also includes a square (9) composed of a thick base (27) and a leg (28). The base (27) has a housing (8) for receiving and housing a base (7) carrying the active component (6). The leg (28) has an orifice (29) whose axis (OZ) passes through the optical center of the active component. A cylindrical sleeve (13) is provided with a flange (14), its axis corresponding substantially to that of the orifice (29). The sleeve (13) is threaded on the intermediate optic (10) connected to an optical fiber (12) and is mounted on the movable part (3) with its flange (14) facing the leg (28). The bracket (9) and the sleeve are aligned so that the axes of the orifice and the sleeve coincide. The end of the optic (10) passes freely into the orifice. The optics are positioned so as to obtain optimum coupling. The square, the sleeve and the optics are then made integral. /P
