| Abstract: | A generalized design method for an optical filter consisting of a dielectric multilayer structure is proposed to get an arbitrary profile of the wavelength dispersion of reflectivity or transmittance. The basic concept of the method lies in the fact that the wavelength dispersion of the reflectivity is approximately determined by taking the inverse Fourier transformation of the refractive index profile of the multilayer structure. Construction of a filter with only three different values of refractive index is described. |
