Abstract
Abstract An optoelectronic transducer for the conversion of lightwaves to electrical voltage or current, or of voltage or current to lightwaves is disclosed, the transducer comprising a fiber optical system (K, L), a support (T) on which an optoelectronic structural element (D) with at least first and second electric leads (E1/D1, E2/D2/DD) is fastened, and a hole (LO) through the support (T) so arranged that the optically active point of the structural element (D) is directed onto the fiber optical system (K, L) across the hole (LO), the hole wall having a metallic coating (DD) which in operation constitutes a section of the first lead of the structural element (D), the first lead capable of sustaining high speed data transmission.
