My POET: I bet they haven't heard about POET.
And that's okay, because it has nothing to do with POET. This graphene-based film might remove the heat faster and better from chips, but it will neither reduce their power consumption nor will it make them faster, let alone integrate optics with electronics or analog with digital.
Could still be interesting to cool down future high-power and/or small node-size POET chips, if applicable.
