Patent ID: 8415608

Claim:
A communications system for sensing a sequence of photons, the system comprising: at least one intensity control device that selects a range of a rate of arrival of the photons that are to be sensed; at least one polarization control device for selecting a polarization of the photons that are to be sensed; at least one focusing element for focusing the photons that are being sensed; at least one frequency selective electromagnetic detector, wherein the at least one frequency selective electromagnetic detector detects the sequence of the photons that are focused from the at least one focusing element, wherein when the at least one frequency selective electromagnetic detector senses at least one photon, the at least one frequency selective electromagnetic detector emits at least one electrical pulse having a voltage that is proportional to an energy level of the at least one photon; and at least one processor for processing the at least one electrical pulse and for de-multiplexing the sequence of the at least one electrical pulse based on the at least one electrical pulse voltage.
