Fractal multilayer structures based on one-dimensional photonic crystals are constructed to generate multiple defect modes. The proposed fractal photonic crystals can produce as many defect modes as desired by adjusting the number of the defect layers. The interaction effect between the defect states of such fractal structures is avoided. Therefore, the frequency, frequency interval, and number of the defect modes corresponding to different kinds of defects can be tuned separately. With perfect transmission and mode controllability, these structures provide an efficient way to fabricate multichannel filters with specific channels.
