Claim:
1. A device, comprising: a first die of semiconductor material, said first die having circuitry including a photon emitter on the front side of the first die, and a beam path on the front side of the first die and positioned to direct a beam of photons from the photon emitter on the front side of the first die, through the semiconductor material of the body of the first die, and to the backside of the first die; a second die having a photon emitter driver circuit, said second die being coupled to the front side of the first die having the photon emitter, for driving the photon emitter; an optical coupler positioned at the backside of the first die to receive the beam of photons from the backside of the first die; and a heat sink thermally coupled to the backside of the first die, made of a heat drawing material and positioned to draw heat energy generated by circuitry including the photon emitter on the front side of the first die, wherein the heat sink defines a recess within the heat sink and the optical coupler is received in the heat sink recess.
