| 摘要 |
A dielectric optical waveguide coupler for optically coupling together two lengths of dielectric optical waveguide consists of a tube having a capillary bore, into which may be inserted, from each end of the tube, the two dielectric optical waveguides to be joined. The capillary bore is tapered at each end to facilitate the insertion of the dielectric optical waveguides. The dielectric optical waveguide coupler may be made by immersing a capillary bore tube with its capillary bore filled with water into an etchant solution.
