%X Based on the principle of one-dimensional photonic crystal super-lattice and coupled optical microcavities,a new scheme to achieve multiple channeled optical filters with flat-top transmission peaks was presented.The traditional cavities of single material were replaced by photonic crystals with finite period,and thus a super-lattice structure was constructed.Using transfer-matrix method,the structural spectra and the influence of the structural and material parameters on the locations and the FWHMs of the transmission peaks were studied.The numerical results show that this structure has a rather wide photonic band gap,in which there are multiple flat-top transmission peaks.These peaks are symmetrical,with high transmission rate and high error tolerance.The locations of these peaks can be calculated exactly,and the strict analytic expression was presented.
