Abstract:
1. An integrated circuit to enhance photon emissions responsive to an input signal within the integrated circuit, the integrated circuit comprising: circuitry to generate the input signal based upon an operable circuit voltage, the circuitry being coupled with a conductor of the integrated circuit, to apply the input signal to the conductor while the integrated circuit is operating, wherein the input signal has a magnitude at or less than the operable circuit voltage; and a beacon coupled with the circuitry at the conductor to generate photon emissions in response to the input signal while enabled and to substantially remain non-responsive to the input signal while disabled, wherein the beacon comprises: the integrated circuit to couple the circuitry with a first external power supply to supply the operable circuit voltage; and the integrated circuit to couple the first end of the channel of the first transistor with a second external power supply to supply the second supply voltage, the second external power supply being distinct from the first external power supply.
