Abstract
We systematically investigate realization of super narrow-pass-band and super narrow-transmission-angle filters with one-dimensional defective photonic crystal hetero-structures through the transfer-matrix method. The structure consists of a few different defective one-dimensional photonic crystal blocks. The influence of the relative bandwidth of the defective layer, the number of periods, and the ratio of index of the high index material to the low index material in the structures were studied. We find that when the relative width factor m and n of the defective layers are even numbers, relatively narrower pass-angle will be achieved. When the number of periods of the structures increases, the pass-angle will decrease exponentially. When the number of periods reaches 12, the pass-angle gets to be less than 0.002 degree. In addition, higher ratio of the two indices in the structures corresponds to smaller transmission angle and narrower wavelength pass-band.
