      In the attached file you will see a simple idea of a classical photon in a spin 1 state. As predicted by QM photons are not simple electromagnetic waves instead they seem to be  structures of ectromagnetic waves of the same frequency ( there is a slight spectrum variation but that is insignificant). Any photon has an intrinsic CW or CCW spin after it has been generated. If two photons one CW the other CCW combine they will form a higher energy photon carrying both CW and CCW angular momentum at the same time by a classical superposition.

Notes.1) In fig 10 the blue line is the petal corresponding to the horizontal filter.
            2) In QM you can't combine photons or split them. However, nothing prevents that in reality. Only emissions and absorbtions (after stabilization on an orbital) are quantitized.  Classical EM waves can easily do that.

P.S. I’ve realised the previous  model was wrong because, first of all, it didn’t use the vector addition correctly.
