A system-in-package includes: a photonic integrated circuit (PIC) including an active photonic component; and an electronic integrated circuit (EIC) stacked on the PIC, the EIC including: an electrical component electrically connected to a landing pad, and a copper pillar embedded in the landing pad and protruding from the landing pad that connects with the active photonic component such that the electrical component is electrically connected to the active photonic component. The landing pad has a larger surface area than a cross sectional area of the copper pillar, and wherein, when viewed from the EIC towards the PIC, the active photonic component on the PIC is offset from the landing pad of the EIC, wherein the offset is sufficient to keep a parasitic capacitance between the landing pad and the active photonic component within a pre-determined threshold level of tolerance.
