comment Is there an optical filter which exclusively passes right or left circularly polarized light?
Thanks @ThePhoton, that's what I'm looking for. It seems to be called a homogenous circular polarizer (en.wikipedia.org/wiki/Polarizer#Homogeneous_circular_polarizer).

Can you justify why this fact is not dependent on your choice of gauge?

Would you be willing to answer another question of mine related to the geometry of $E$ and $B$ for plane waves? physics.stackexchange.com/questions/173496/…

Doesn't this depend on an arbitrary choice of $\mathbf{A}$? (Refer to physics.stackexchange.com/questions/173499/…)

This doesn't address my question. Can you modify your answer?

In specifying that plane wave solution, aren't you choosing $\mathbf{A}$ to be perpendicular to $\mathbf{k}$?

Yes, phasors fall under that category
