Polarization-maintaining fiber at the photon level

  1. Jun 23, 2009 #1
    Could someone please explain to me what a linear optical polarization, such as one that is guided by a PM fiber, is made up of in terms of photons.

    I think I understand that 50% of the photons are left circular, and 50% are right circular. Is this correct?

    Supposing I added some property to just the left circular ones and then looked for this property 100 metres down the fiber - would it still be just the left circular photons that contained it? Or would some of the other photons have become left circular during that time. Are the photons polarizations constantly changing, or are they stable?

    Sorry for the garbled mess, but I am in need of some clear explaining.

    Thanks.
