摘要
A wide band-pass filter has been presented based on one-dimensional metallo-dielectric ternary photonic crystal. ZnS, Ag and MgF2 are used as the materials of the photonic crystal. The forbidden and allowed bands of the photonic crystal are determined by using the band-edge analysis. The result indicates that the filter has a wide pass band in the visible region and it can block ultraviolet and infrared light. Simulation of the transmission spectra shows that the filter has decent transmittance in the pass band at broad angle incidence ranging from 0A degrees to 70A degrees, which can meet the need of practical use.
