Abstract
An optical via within a printed circuit board (PCB) to route optical signals from one level to another through the PCB. The optical signals entering the optical via from an optoelectronic device, or other source, may be routed by an optical waveguide to enter other optical vias to a destination for different purposes. The source of optical signals may be mounted to the PCB or it may be at a distance, with the optical signals being coupled to or away from the optical via by means of optical waveguides.
Claims9
A printed circuit board (PCB) comprising:
- a top mounting surface;
- a recessed portion having a recessed mounting surface that is substantially parallel to the top mounting surface;
- an optical via extending from said recessed mounting surface to an exit port in said printed circuit board;
- a first optoelectronic device mounted on said recessed mounting surface, said first optoelectronic device configured to transmit or receive an optical signal through said optical via;
- and
- an integrated circuit (IC) mounted onto said top mounting surface such that said IC is positioned directly above said first optoelectronic device.
