Abstract
A chip-to-chip optical interconnect includes a substrate, an optoelectronic die, and a waveguide structure. The substrate includes an optical via passing through the substrate. The optoelectronic die is disposed on the substrate and aligned to optically communicate through the optical via. A waveguide structure is positioned proximate to the substrate and aligned with the optical via to communicate optical signals with the optoelectronic die through the optical via.
