| 摘要 |
An optical waveguide is described which has a core and a sheath, each of which is made of a fully fluorinated fluorocarbon material. In particular, a fully fluorinated Teflon material such as Teflon AF 1600 or Teflon AF 2400, or a mixture thereof, is suitable as the fully fluorinated fluorocarbon. The optical waveguide is optically transparent around the 1300 nm and/or 1550 nm wave band. Furthermore, the core of the optical waveguide may have a refractive index that is higher than the refractive index of the sheath. The optical waveguide is suitable for use as, for example, an integrated optical waveguide for transmitting information in optical telecommunications.
