Tunable Study of Frequency Selective Filter Based on Photonic Crystal
An effective design of frequency Selective Filter in a two-dimensional (2-D) photonic-crystal (PC) was proposed. At first, a branch-missing-line photonic-crystal waveguide by inserting three different PC materials to the crotch was investigated. By analyzing band gaps of the filter, the characteristics of a frequency selective filter were discussed. Second,by choosing different radii of PC rods in the crotch of a branch waveguide,we could similarly obtain the required frequency of the electromagnetic wave. Finally,by using Thermo-optical effect to change dielectric constant, the operating wavelength of the device could be tuned.
