ABSTRACT:
An object of the present invention is to provide an optical wave guide element for making the miniaturization of the entire device including the optical wave guide element possible, by connecting optical fiber for incoming and outgoing radiation to the optical wave guide element, so that the optical wave guide element and the optical fiber are positioned at an angle of 90°, as well as to provide a manufacturing method for the same.
