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 lensis adjusted by an iris diaphragmin which the hole diameter can be changed from 1 mm to 12 mm. An image of the self-written optical waveguidebeing fabricated is taken with a CCD camera, and image processing of the image is executed in real time by an image processing device. The taper angle of the self-written optical waveguideis measured, and the taper angle of the self-written optical waveguidecan be desirably increased or decreased by changing the diameter of iris diaphragm
