Abstract
Embodiments herein relate to systems, apparatuses, techniques or processes directed to a package that include a substrate with a glass core, with one or more grounded coplanar waveguides placed on one or both surfaces of the glass core. The one or more grounded coplanar waveguides may then be used for high-speed communication between two dies, such as a compute die and a memory die, coupled with the substrate. Other embodiments may be described and/or claimed.
