Abstract: We propose a polarization-dependent spatial phase modulation method to purify the two-photon polarization entanglement generated by the biexciton cascade decay in a single semiconductor quantum dot. In principle, our method can completely compensate the random phase acquired from the decay of the non-degenerate exciton states in time domain. In frequency domain, our method is equivalent to shifting photon frequency according to its polarization. The method can be applied immediately by existing experimental set-ups.
