Valid corollaries of polarization-separated color attributes for a multi-layer dielectric structure

Abstract

Herein, four corollaries for polarization-separated color attributes have been firstly proposed and experimentally verified based on the systematical investigations of a multi-layer dielectric structure L/(Ge/ZnS)3 (L stands for surface ZnS). Specifically, for different spectra responses to surface thicknesses dL (30, 60 and 90 nm) and incident angles θ (45°, 60° and 75°), color attributes of synthesis, s-polarization (s) and p-polarization (p) are systematically induced as: arithmetical averaging properties of luminance factors Ysynthesis% = (Ys% + Yp%)/2 or tristimulus values (Tv) Tv-synthesis = (Tv-s + Tv-p)/2; collinearity of synthetic and polarization-separated chromaticity coordinates (CCs); constant mathematic relation of Tv(s) > Tv(p); synthetic CCs partial to s-polarized CCs as dp-synthesis > ds-synthesis. These corollaries can be further generalized to common dielectric multi-layer structures due to the general derivation without any restrictions of the intrinsic parameters.
