Abstract

Two group unit cells of second order Sierpinski carpet photonic crystals are constructed, where the dielectric pillars in the unit cells are geometry structure of isosceles triangle. Photonic bands of the fractal photonic crystals are calculated by Order-N method. The result shows that the center frequency of guided bands vary with changing the structure shape of the unit cells, and with variety of the apex angle of the isosceles triangle pillars, it can be seen that the capacity of tuning the frequency of guided bands for big triangle dielectric pillar in the middle of the unit cell is stronger than that for small ones all around the unit cell.
