| 英文摘要 | In a triangular-sectioned prism 11 having a first plane 11a opposite an end face of an optical fiber 12, a second plane 11b opposite a light receiving element 13 and a third plane 11c which reflects received light 21 incident thereon from the optical fiber 12 toward the second plane 11b and transmits transmission light 22 emitted from a light emitting element toward the first plane 11a, a cylindrical member 32 of a refractive index larger than that of the prism 11 is embedded in that area of the prism 11 which is opposite the end face of the optical fiber 12. The cylindrical member 32 effectively suppresses the leakage therefrom of light, providing increased optical coupling efficiency as compared with that achievable by use of a mere prism structure. |
