Abstract
A system for coupling optoelectronic devices, associated electrical components, and optical fibers is described. The system includes a substrate to which optoelectronic devices and at least some of the associated electronic components are formed on or formed using the substrate material. The substrate is further configured to receive and attach to one or more optical fibers. The system can be used to form transceivers for multiplexing and/or demultiplexing electronic information.
