Single photon structure model and multi-photon composite monomer

This paper has proposed a single-photon structure model based on both the Maxwell wave equation and canonical quantization results of free electromagnetic fields under gauge conditions. Model assumption: There are only right-spin single photon and left-spin single photon, and their spin angular frequency (ω=2πν) is their spin angular velocity. By studying the bunching properties of two single photons, it was found that homo-frequency right-spin photons and left-spin photons could be superimposed into linearly polarized (LP) 2-photon monomers. Two homo-frequency and parallel LP 2-photon monomers with a phase difference of 90° can be superimposed onto an LP4-photon monomer. This monomer has been proven to be a normal unit of light.
