Co-relation between interference and polarization

  1. May 16, 2011 #1
    Let's say we send two photons at same time through double slit:

    Would interference pattern form if:

    1. Both the photons are of different polarization? (i.e. one left polarized and the other right)
    2. Both the photons are of same polarization?

    1. There will be a degree of destructive interference, so a distorted pattern would emerge.
    2. Yes.

    thanks Dr Chinese.

    now if we modify the double slit experiment (one photon at a time) as below:

    1. we place a polarizer before the slits
    2. we don't place a polarizer (i.e. simply the "classic" double slit, single photon at a time experiment)

    Would the interference pattern between 1 and 2 look different?

    Should get an interference pattern in both cases.
