METHOD FOR MANUFACTURING OPTICAL WAVEGUIDE HAVING INCLINED END SURFACE

摘要

Disclosed is a method for manufacturing an optical waveguide having an inclined end surface, the method comprising: a perpendicular cutting step of causing a router bit, which has a predetermined inclined surface at a leading end portion, to penetrate in a perpendicular direction to a predetermined depth while cutting the optical waveguide, from above a position at which an inclined end surface of the optical waveguide is to be formed; and a parallel cutting step of moving the penetrated router bit in parallel or perpendicular direction relative to the longitudinal direction of the optical waveguide, while maintaining the height of the router bit, to form thereby an inclined end surface. The object of such a method is to provide a method for manufacturing an optical waveguide having an accurately disposed inclined end surface.
