ABSTRACT:
A taper angle of a self-written optical waveguide to be formed is increased or decreased at a desired position. A range of light (aperture number) condensed by a focusing lens31is adjusted by an iris diaphragm22′in which the hole diameter can be changed from 1 mm to 12 mm. An image of the self-written optical waveguide51being fabricated is taken with a CCD camera70, and image processing of the image is executed in real time by an image processing device71. The taper angle of the self-written optical waveguide51is measured, and the taper angle of the self-written optical waveguide51can be desirably increased or decreased by changing the diameter of iris diaphragm22′.
