Bend optical waveguide structure, optical sending and receiving module, and optical connector module

摘要

P To provide a bending optical waveguide structure that can achieve cost reduction and productivity improvement and to provide an optical transmission and reception module and also an optical connector module that include the bending optical waveguide structures. PSOLUTION: The bending optical waveguide structure 24 is for optically coupling a light emitting part 22 and an optical fiber 23 or for optically coupling a pair of optical fibers 23. The structure includes: a light transmissive block 28 which is formed in a shape almost constituting one of a plurality of axially split parts of a column; and an optical waveguide 29 which is integrated and homogeneous in material with the circular-arcuate face 30 of the block 28 which projects from the circular-arcuate face 30 to extend in the circular-arcuate direction and which has a projected cross section. Furthermore and the outer face extending in the circular-arcuate direction of the optical waveguide 29 is formed in mirror finish. PCOPYRIGHT: (C)2011 and JPO& INPIT
