METHOD OF CONNECTING OPTICAL WAVEGUIDE WITH OPTICAL FIBER

摘要

In connecting an optical fiber (15) to an optical waveguide (12) formed in a waveguide substrate (11), a first groove (13) is formed in the substrate to expose one end of the optical waveguide (12), and a second groove (14) is formed at right angles with the first groove. The optical fiber is fitted into the second groove in a manner that the end surface of the optical fiber (15) is brought into intimate contact with the end surface of the optical waveguide (12), and the optical fiber is secured in the second groove with an adhesive. Thus, there is provided a method of connecting the optical fiber and the optical waveguide together maintaining excellent temperature characteristics and impact resistance.
