In this discussion of polarization, it says
For linearly polarized light, the $x$- and $y$-components are exactly in phase and therefore rise and fall together
Can it therefore be assumed, then, that if light is linearly polarized, it is in phase? More specifically, if two photons, separate from each other, are linearly polarized, are they in phase with each other?
I apologize if this exhibits a misunderstanding of the topic; I'm rather unfamiliar with optics.
