I assumed, when I read the above, that you intended to determine E by measuring the electrical power consumed by the photon source. If that assumption is incorrect, then how do you plan to determine the value of E? You cannot, as I have already noted several times, simply count the clicks of a photon detector, because it is precisely the efficiency of photon detectors--i.e., the ratio of photons emitted to photons detected--that we are trying to determine. If that efficiency is very low, if in fact clouds of photons are emitted down both pathways for every detection in these so called "single photon self interference" experiments, then there is in fact not a shred of evidence that the much ballyhooed phenomenon of self-interference even exists.
Therefore I repeat: how do you propose to determine the value of E, if not by measuring the electrical power consumed by your photon source?
