| Zusammenfassung: | A relatively inexpensive and relatively efficient coupler is obtained by connecting two fiber collections (41,42) with a polymer material, provided the numerical aperture of the two collections are relatively well-matched to each other and to the polymer region. This efficiency is achieved despite relatively large mismatches in the refractive index of the resin material relative to the fibers. Couplers for optical backplanes are produced in one embodiment utilizing plastic materials. In this technique, a collection of fibers is inserted on each end of an enclosure such as a tube (43) that is filled with a polymer that is subsequently cured. |
