Photon Diameter Measurements

The 1985–89 Hunter-Wadlinger electromagnetic theory of the photon predicted that the photon is a soliton-wave with the shape and size of a circular ellipsoid of length λ the wavelength), with a diameter of λ / π. This prediction is being tested by three diameter measurements: 1) those carried out in 1985–86 with microwaves, 2) in progress measurements on 10 micron photons from a CO2 laser, and 3) an imminent experiment with monochromatic visible light (400–800 nm).
