Utilization of double-film to Control Total Reflected Amplitude of Polarized Light

This work aims to increase the flexibility of a frequency converter model by introducing a double-filmed semiconductor substrate. Here the thickness of the two films acts as an additional variable together with the incident angle to further satisfy the phase-matching condition during the frequency conversion process. Generalized expressions for the reflected amplitude have been formularized for both p-polarized and s-polarized lights. Different isotropic semiconductors are used as film (calcium fluoride, lead fluoride) as well as substrate (zinc selenide) to analyze the computer-aided simulation for a graphical representation of the proposed scheme.
