can some one explain 2 me the basis of photon polarization ...?
See any freshman physics book, or one more advanced, to learn that electromagnetic waves are transverse, and that does it --transverse => two polarization states. Very basic stuff.

Photons are "generated" when a charge moves in a specific way. If
the charge moves up and down, the photons that fly off will be polarized
linearly.
If the charge spins around, they will be polarized circularly and one of two
ways depending on which way it spins, CW or CCW.

It's called "helicity operator eigenvalues". Why the photon has two instead of 3, well, it's called "gauge invariance". "Photon polarization" is a bit of an oxymoron, as "polarization" is typical to wavelike phenomena, while "photon" is a particle.
