Patent ID: 8004080

Claim:
A module, comprising: a module substrate; a first integrated circuit having a first major surface, a second major surface, a first edge, a second edge, and a third edge, wherein the first integrated circuit has optical circuits having ports on the first edge and electronic circuits having ports on the second edge, wherein physical and electrical connections are made to the module substrate at the second edge; a second integrated circuit having a first major surface, a second major surface, a first edge, a second edge, and a third edge, wherein the second integrated circuit has optical circuits having ports on the first edge of the second integrated circuit and electronic circuits having ports on the second edge of the second integrated circuit, wherein physical and electrical connections are made to the module substrate at the second edge of the second integrated circuit, the first major surface of the second integrated circuit is parallel with and adjacent to the second major surface of the first integrated circuit; a heat sink having a backplane adjacent to the third edges of the respective first and second integrated circuits, a first portion along the first major surface of the first integrated circuit, a second portion along the second major surface of the second integrated circuit extending from the backplane, and an insert between the first major surface of the second integrated circuit and the second major surface of the first integrated circuit.
