In order to study the polarization property of 1-D photonic crystal,transfer matrix method was used for calculation.It is found that at normal incidence, the change of the refractive index and the refractive index modulation will not influence the gap position and the gap for p light is coincident with that for s light; however, the lager the refractive index, the smaller the gap; the lager the modulation of the refractive indeed, the larger the gap.At oblique incidence,with the increase of the modulation of refraction index, the gap position moves to lower frequency and the gap becomes larger; with the increase of the refraction index, the gap position moves to lower frequency and the gap becomes smaller, especially the gap for s light becomes smaller obviously.The change of the thickness of the media down't influence the position of the gap of the two different polarizations.The conclusion is useful for the design of 1-D photonic photonic crystal polarizers.
