Field distribution of two kinds of polarized light in 1-D photonic crystal

In order to study the field distribution of 1-D photonic crystal, the formula of the light intensity distribution of TM wave in 1-D photonic crystal was deduced based on the characteristic matrix and the intensity of TM wave and TE wave in 1-D photonic crystal was analyzed. The results show that the light intensity of TM wave and TE wave decreases with the increase of propagation depth in forbidden band of 1-D photonic crystal. The light intensity of TM wave and TE wave does not decrease with the increase of propagation depth in conductive band of 1-D photonic crystal. The study is helpful for the understanding of forbidden band and conductive band in TM wave and TE wave.
