Abstract

Classical light fields are considered physical examples of nonquantum entanglement\cite{Eberly2011}. We apply concurrence and Schmidt approach to evaluate the degree of entanglement for a generalized polarization state that Qian and Eberly suggested, and we obtained an analytic form of the general entanglement state for planar polarization states of classical light.
