Abstract

A transceiver comprising a plurality of CMOS chips may be operable to communicate an optical source signal from a semiconductor laser into a first CMOS chip via optical couplers. The optical source signal may be used to generate first optical signals that are transmitted from the first CMOS chip to optical fibers coupled to the first CMOS chip via one or more optical couplers. Second optical signals may be received from the optical fibers and converted to electrical signals via photodetectors in the first CMOS chip. The optical source signal may be communicated from the semiconductor laser into the first CMOS chip via optical fibers in to a top surface and the first optical signals may be communicated out of a top surface of the first CMOS chip. The electrical signals may be communicated to at least a second of the plurality of CMOS chips comprising electronic devices.
