Patent ID: 7917042

Claim:
A high speed optoelectronic receiver, comprising: a high speed optical input adapted to receive an optical data stream; a photodiode connected to the optical input adapted to produce an electronic data stream corresponding to the optical data stream; a demultiplexer having an input adapted to receive the electronic data stream and produce a plurality of lower data rate tributary data streams; and a planar transmission line connected between the photodiode and the demultiplexer and adapted to connect the electronic data stream from the photodiode to the input of the demultiplexer, said planar transmission line including a planar dielectric substrate having a first side and a second side; a strip of conductive material formed on the first side of the substrate; a first ground plane formed on the first side of the substrate and insulated from the strip of conductive material; a second ground plane formed on the first side of the substrate and insulated from the strip of conductive material; a third ground plane formed on the second side of the substrate; and at least one via from the first to the second side of the substrate adapted to connect at least one of the first and second ground planes to the third ground plane.
