Abstract

PURPOSE:To input the light from a light emitting element at larger quantity into optical fiber by polishing obliquely the end face of a fiber array consisting of an adhesive agent which is injected between a silicon substrate and a pressing glass material and has the refractive index approximately equal to the refractive index of the fiber. CONSTITUTION:Grooves are formed to a silicon substrate 1 by anisotropic etching. Optical fibers are installed in the V-grooves of the substrate 1, and a glass material 3 is pressed thereto. An adhesive material 4 is injected between the substrate and the glass plate to fix both. The adhesive material 4 which has the refractive index approximately equal to the refractive index of the fibers 2 and the plate 3 is used. Then, optical coupling is effected efficiently and easily with a plane socket element or a plane light emitting element, and the light from the light emitting element is inputted at larger quantity to the optical fiber.
