A hybrid electro-optical package for an opto-electronic engine. The package includes a carrier substrate, and a package base. Electrical vias and an optical via of the carrier substrate communicate between a back side and a front side of the carrier substrate. The package base is coupled to the carrier substrate by intra-package electrical interconnects. The carrier substrate is to interconnect electrically with an opto-electronic component mounted on its back side, and includes an optical aperture at its front side for communication of optical signals. Similarly, lands disposed at a front side of the package base provide for communication of electrical signals to an integrated circuit and the opto-electronic component. A system and an opto-electronic engine that include the hybrid electro-optical package are also provided.
