Effect of Structure Parameter of One-Dimensional Doped Photonic Crystal on Photonic Band Gap Structure

The properties of band-gap of one-dimensional doped photonic crystal are studied by using numerically method based on the transfer matrix method.The result shows that a narrow conduction band appears in the centre of forbidden band in one-dimensional doped photonic crystal.The depth of conduction band appears in the centre of forbidden band has a maximum,which was caused by the number of layers of the second half of impurity where the first one was fixed.It shows that the forbidden band center's conduction band depth was still biggest by means of changing basic level thickness.
