Abstract:
1. An optical multi-chip module (MCM) comprising: a leaded package comprising a bottom, sides, and interconnection leads extending through the sides; a printed circuit board (PCB) overlying the package bottom wherein the PCB comprises a top surface having a first die contact region with a plurality of electrical interfaces, and a second die contact region with a plurality of electrical interfaces, where the first die contact region is formed in a PCB top surface first recess configured to receive an optical component die, and where the plurality of first die electrical interfaces is connected to the plurality of second die electrical interfaces via transmission lines formed in the PCB; a first optical component die comprising a bottom surface with an area about matching the PCB top surface first recess such that said first optical component die substantially fills said first recess when placed therein, and with a plurality of electrical interfaces connected to the first die electrical interfaces, the optical component die further comprising a plurality of optical ports on a top surface and a microlens overlying each optical port; a first electrical component die comprising a bottom surface with a plurality of electrical interfaces connected to the second die electrical interfaces, and a top surface with a plurality of electrical interfaces; a plurality of wire bonds connected between the plurality of first electrical component die top surface electrical interfaces and the package interconnection leads; and, a cover assembly overlying the package, comprising a connector with an optical port and a microlens configured to communicate with each optical component die optical port, and a plurality of fiber ports to accept optical fibers.
