The high-polarized single-photon emission in single anisotropic InGaAs quantum d ots excited by linear pulse excitation was discussed. The expression of the pola rization and cross relaxation between two orthogonal eigenstates was given. It w as revealed that the cross relaxation increased with intensity of the excitation , which resulted in the decrease of polarization factor with the input pulse a rea.
