Claim Text:
1. An apparatus comprising: a first substrate layer of an integrated circuit (IC), the first substrate layer including an optical component; an insulator layer on the first substrate layer; a second substrate layer separated, at least in part, from the first substrate layer by the insulator layer; a transistor on the second substrate layer, the transistor being connected to the optical component a waveguide on the first substrate layer, the waveguide being connected to the transistor; and a heat transfer via (HTV) extending vertically through a horizontal portion of the insulator layer and the first substrate layer, the HTV being adjacent to the second substrate layer and aligned vertically with the transistor, wherein the thickness of the insulator layer is greater than a thickness of the first substrate layer.
