PCT No. PCT/DE90/00243 Sec. 371 Date Oct. 25, 1991 Sec. 102(e) Date Oct. 25, 1991 PCT Filed Mar. 26, 1990 PCT Pub. No. WO90/13835 PCT Pub. Date Nov. 15, 1990.A light-waveguide device has a light waveguide having a circumference provided with a groove, and a coupling element having a carrier and at least one of a light-sensitive transmitting component and a light-sensitive receiving component for coupling an optical radiation in and out of the light waveguide. The carrier is T-shaped and has a base surface and a central support. The at least one light-sensitive component is arranged on the T-shaped carrier and forms with the base surface of the T-shaped carrier an angle alpha . The central support of the T-shaped carrier is inserted in the groove so that the at least one light-sensitive element is inserted with its surface at least partially in the groove so that from the groove a portion of the optical radiation of the light waveguide falls on or exits from the at least one light-sensitive component and the portion of the optical radiation can be tapped as an electrical signal at the light-sensitive transmitting component or an additional portion of the optical radiation can be fed to the transmitting component. |
