Patent ID: 7092597

Claim:
A bidirectional transmitting and receiving device, comprising: a transmitting area of a first size; a receiving component comprising a receiving area of a second size; and coupling optics configured to couple light between the transmitting component and the receiving component on the one hand, and an optical waveguide to be coupled thereto on the other hand, wherein the coupling optics comprise two imaging component comprising an emission systems that are arranged one behind the other such that the light that is emitted from the transmitting component is imaged by the first imaging system onto an intermediate plane on which the receiving component is located, and in the process passes through the receiving component or passes by it at a side thereof, and wherein the second imaging system images firstly the light that is emitted by the transmitting component from the intermediate plane onto an end surface of the optical waveguide, and images secondly the light that is emitted by the optical waveguide onto a receiving area of the receiving component.
