Abstract :
The photonic crystal device is potentially important for upper-millimeter and terahertz applications and will create a new breakthrough in modern electromagnetic wave circuits. The propagation loss of photonic crystal waveguides, which is related to the confinement property of guided mode, is thought one of key factors in device designs. The dispersion characteristics of the PhC structure are firstly calculated by using the plane wave expansion method. Then the wave propagation properties of the PhC straight waveguides, T-junctions are numerically investigated as well as a bandpass filter based on microcavity.
