PROBLEM TO BE SOLVED: To easily manufacture an optical path conversion mirror at an arbitrary position of an optical waveguide at an arbitrary angle, and to contribute to the reduction of cost. SOLUTION: An optical waveguide 20 is cut by moving a heated knife blade 30 across the optical waveguide with the knife blade maintained at a predetermined angle. At that time, by maintaining the temperature of the knife blade 30 at a temperature not lower than the glass transition point of the optical waveguide 20, a portion, in contact with a blade edge face 35a of the knife blade 30, of the optical waveguide 20 softens to be planarized along the blade edge face 35a. Thus the optical path conversion mirror is formed as a flat cut face at the part at which the blade edge face 35a passes. COPYRIGHT: (C)2010,JPO&INPIT |
