In this paper, we present a new class of broadband spectral filters based on aperiodic multilayer structures that reduce the required number of layers. Furthermore, the filter performance is optimized by Genetic algorithm, which is particular useful for optimizing arbitrary shape broadband filter. Quantitative computer simulation results are provided, which are consistent with theory. We believe that thee unique broadband filters may have a variety of applications in th area of broadband spectroscopy and hyperspectral imaging.
