Abstract: Making use of the feature that the permittivity of Kerr medium changes with the incident light, a new-type filter with Kerr medium is designed by controlling the side length of dielectric cylinder of coupled cavity to change the frequency. This filter consists of point defect, micro-cavity, download wave-guide, reflection heterojunction and main wave-guide, and the square GaAs dielectric cylinder is used in coupled cavity. The simulation calculation made through COMSOL Multiphysics shows that the filtering efficiency of this new filter can reach 99.7%.

Key words: Kerr medium, heterjunction, two-dimension alphotonic crystal, filter
