Lecture
This lecture covers the concepts of linear and circular polarization of light, including the Jones vector representation, elliptical polarization, and natural light as a sum of random polarizations. It also discusses the angular momentum associated with circular polarization, the Poincaré sphere to describe polarization states, and the Stokes parameters to quantify polarization. The relationship between polarization and the spin of photons is explored, along with the concept of partially polarized light.
