Majid Seifan; Alireza Malekijavan; Alireza Monajati Kashani

By creating point defects and line defects in photonic crystals, we reach the new sort of photonic crystals. Which allow us to design photonic crystals filters. In this type of photonic crystals the ability to tune up central frequency of filter is important to attention. In this paper, we use foregoing points for designing photonic crystal filters. The main function of this type of filters is coupling between shield of point defect modes and directional line defect modes. By using liquid crystals in this structures we can tune up the central frequency. We exert electric field to excite liquid crystals and design photonic switch. This provided filter is promising to miniaturize integrated circuit photonic crystal.
