Abstract

PURPOSE:To prevent the chipping of the edge of an optical fiber and to facilitate production by embedding the optical fiber into the groove on a substrate surface and executing the polishing of an optical fiber terminal after optical sheet glass is brought into light contact with the optical fiber and is adhered together with the optical fiber to the substrate. CONSTITUTION:The optical fiber 13 is embedded into the V-groove 12 on the front surface of the silicon substrate 11 by partly exposing this fiber in such a manner that the terminal of the optical fiber 13 faces the open end on the front surface of the groove 12. The front surface thereof is covered with the optical sheet glass 15 and the optical fiber 13 is fixed by an adhesive 14 into the groove 12. The end face of the substrate 11 is worked together with the optical glass 15 and the optical fiber 13 to about 45 deg. angle. The end face of the fiber is simultaneously worked. Since the optical fiber 13 is securely fixed between the substrate 11 and the optical glass 15, the dislodgment of the optical fiber 13 during the working does not arise. The danger of the chipping of the edge of the optical fiber 13 during the working of the end face of the optical fiber 13 is lessened in this way and the improvement in the productivity is made.

In this example, the optical device 41 is arranged vertically on something like an L subtitle board 44 in order to make the optical axes of the optical fibers 13 parallel to each other.
