Design and synthesis of a modified band-pass optical filter

The reflection and transmission coefficients of two-component and three-component dielectric multilayered periodic structures (2CODMS and 3CODMS) are derived using the transfer matrix method. The width of the high reflectance zone in the case of two-and three-component systems is derived and computed using suitable parameters. Numerical calculations for long-and short-wavelength cutoff band-pass filters of various structures are shown in a three-component system. Comparison is also done for 2CODMS for long-and short-wavelength cutoff filters. Spectral properties of interference reflection filters of the type G(XY)A], whose components represent long-wavelength cutoff X] and short-wavelength cutoff Y], are also studied. The reflection and transmission bandwidth of the high reflectance zone is presented. Optimization is done in three-component systems to make it suitable for ideal long-and short-wavelength band-pass filters.
