A circularly polarized electromagnetic wave can be thought of proper combinations of orthogonal linear polarized waves, and a linear polarized wave can be thought of proper combinations of left and right circularly polarized waves. It seems one type of wave is no more fundamental then the other, circularly polarized verses linear polarized. In the quantum field theory of photons is this still the case or not? Can I think of both linear and circular polarized classical electromagnetic waves as proper combinations of many spin 1 particles? Is there another way of thinking of linear and circular polarized classical electromagnetic waves? Is it the spin 1 that is fundamental? Hope I'm clear, thanks for any help! Thanks for your help!
