Integrated electrical/optical interface with two-tiered packaging

Abstract:

An improved chip package, and methods for fabricating the same are provided that utilize two tier packaging of an optical die and another die commonly disposed over a substrate. In one example, a chip package is provided that includes an optical die, a core die, and an electrical/optical interface die are all disposed over a common substrate. In one example, a first routing region is provided between the core and electrical/optical interface dies, a second routing region is provided between the electrical/optical interface die and the optical dies, and a third routing region is disposed between the substrate and the core and electrical/optical interface dies.
