Abstract
An integrated circuit (IC) package substrate comprises an upper surface, a lower surface opposite the upper surface, and an outer side surface extending between the upper surface and the lower surface. At least one optical path is in a plane of the IC package substrate, and at least one vertical optical coupler at an upper or lower surface of the IC package substrate is optically coupled to the optical path.
