/ f9 n. L6 ?2 M2 O) uAbstract：The possibility of designing optical filters using photonic crystals technique was studied in this paper. A dualchannel optical filter was designed using photonic crystal concept and prepared by/on Beam Assisted Deposition （IBAD）. The influence of thickness error of each layer to optical character was also discussed, and the result shows that the most sensitive layer is defect-layer. So it is possible to design dual-channel filters using one-dimension photonic crystals concept.
