Analytical Study of Filters Dimensions and Spectral Thermal Effects on Optical Filters Operation Performance Characteristics

We study the different optical filters design considerations over wide range of the operation conditions in near infrared optical spectrum transmission region. There are many operating conditions parameters describing optical filter properties such as the amount absorbed electromagnetic radiation which depends on the operating signal wavelength; the amount of the absorbing material in the filter thickness; and the absorption coefficient of the material at that wavelength. Filter modulation depth, filtration signal quality, filter delay time, filter bit error rate, and filter correction are the major interesting performance parameters in the current study. Best candidate materials based optical filters are used which namely barium fluoride (BaF2), and zinc selenide (ZnSe) and compared with published measured works. Our results are validated against published experimental studies and show a good agreement and matching.
