An efficient method to perform procrustean distillation and concentration for quantum entanglement has been proposed by using one-dimensional anisotropic photonic crystal (PC). The Clauser-Horne-Shimony-Holt parameter for entangled pure state, the quantum relative entropy and linear entropy for mixed state have been calculated theoretically. It is found that the efficiency of such a method is not only much higher for the distillation of non-maximally entangled pure states than those using partial polarizers, it is also good at the concentration for the mixed states. Both the purity and the degree of entanglement of the mixed states can be improved simultaneously several times by using such a method. Another advantage of the scheme is that it can be widely adjusted by a proper choice of the structural parameters of the PC and the external field. A realizable example by using liquid crystals has also been designed and discussed.
