PURPOSE:To reduce the deterioration in the coupling efficiency and output fluctuation due to temperature variation of the titled device in the course of manufacture, by positioning optical fibers under a condition where the fitting surfaces of the 1st and 2nd fixing jigs are always pulled from each other with fixed negative pressure by the force of magnets and only slight unevenness which is equivalent to machining accuracy exists and fixing the optical fibers to each other at the time of maximum coupling efficiency. CONSTITUTION:When a ferrule holder 12 which becomes the 2nd fixing jig is formed of a metallic material which can be attracted by a magnet 8, the legs of the ferrule holder 12 are always closely contacted with the magnet 8 with negative pressure and, even when moved in x-z directions, the ferrule holder 12 never tilts. Moreover, since a magnet holder 9 which constitutes part of the 1st fixing jig covers the upper surface of the magnet 8 leaving part for passing light uncovered and magnetic force can be transmitted, the legs of the ferrule holding 12 are closely contacted with the magnet holder 9 and metal fixing of resistance welding, etc., can be made. |
