Device for transmitting optical signals has an optical wave-guide with a light-conducting core with coated layers causing reflection of light guided in the core.

摘要

An optical wave-guide (OWG) (3) guides light (6) and has scatter centers (SCs) (7) formed by an electrode in a locally limited area (5). Light spread in the OWG is scattered on the SCs so that scattered light spreads in all directions. Light (8) from an external source can be beamed onto the OWG. If this light falls on the SCs, this light is then also scattered in all directions An Independent claim is also included for a method for coupling a source for emitting light and a receiver for receiving light onto an optical wave-guide made up of light-conducting core with coated layers that cause reflection of light guided in the light-conducting core.
