Optical filtering properties in a multichanneled transmission filter based on one-dimensional photonic crystal containing the coupled defects are theoretically investigated.The resonant peaks designed to be located within band gap of defect-free crystal.The number is directly equal defects.The positions can tuned by varying refractive index defect layer.In addition, extremely produced adding Bragg mirrors at front and rear sides structure.
