Electromagnetic Eigen Characteristics of Optical Couplers Consisting of Multi Optical Waveguides with Cross Sections of Circular Ring Parts
Details
Optical communications, optical information processings and optical memories using coherent optics generated from lasers are repidly developped and optical systems using bulk optical circuits, bulk optical components and optical fibers are used for these information systems. As optical integrated devices of integrated optics, mostly semiconductor lasers and optical detectors are well applied. However, optical integrated devices and circuits have not been accomplished for practical application, except external optical modulators. Particularly, connection technologies for optical fibers and integrated circuits must be well developped for practical systems. The author has studied fiber type and single integrated type connectors and investigated those connection and transformation characteristics. In this paper, electromagnetic eigen characteristics of now type optical multi-fiber bundles and optical couplers consisting of multi waveguides with cross section parts of circular ring sections are discussed, as mathematical boundary problems. Rigorous boundary problems of electromagnetic fields are shown, and technical applications of optical couplers consisting multi-waveguides with circular ring sections, are discussed
