Described herein are photonic communication platforms and related packages. In one example, a photonic package includes a substrate carrier having a recess formed through the top surface of the substrate carrier. The substrate carrier may be made of a ceramic laminate. A photonic substrate including a plurality of photonic modules is disposed in the recess. The photonic modules may be patterned using a common photomask, and as a result, may share a same layer pattern. A plurality of electronic dies may be positioned on top of respective photonic modules. The photonic modules enable communication among the dies in the optical domain. Power delivery substrates may be used to convey electric power from the substrate carrier to the electronic dies and to the photonic substrate. Power delivery substrates may be implemented, for example, using bridge dies or interposers (e.g., silicon or organic interposers).
