    More information on polarization from the Los Alamos site:
    http://www.lanl.gov/science/centers/quantum/light.shtml
    
    and wouldn't you know it - polarization has its own site, with limited info:
    http://www.polarization.com/
    
    and Wikipedia, as usual, is worth looking at:
    http://en.wikipedia.org/wiki/Polarization
