Abstract:
1. An integrated circuitry structure, comprising: a thermal zone and a non-thermal zone of the integrated circuitry structure, the thermal zone having high thermal activity needing greater heat transfer than the non-thermal zone having low thermal activity; an optical layer comprising optical waveguides within a first material having a first thermal conductivity, the optical waveguides bundled into a plurality of sets of closely spaced optical waveguides substantially throughout the thermal zone and individually spaced further apart substantially throughout the non-thermal zone; and a heat-conductive material, having a second thermal conductivity greater than the first thermal conductivity, disposed between the sets of bundled optical waveguides in the first material of the thermal zone, for transferring heat from at least the thermal zone through the optical layer to a heat sink.
