Paper Abstract

Dielectric multilayer stacks consisting of repeated pairs of high and low index quarter-wave layers are often used for beamsplitters. At oblique angles of incidence, such coatings typically have a fairly high polarization ratio, i.e., different reflectance, transmittance and phase for the two orthogonal polarization planes s and p. We use a special refining computer program based on a damped least squares optimization technique to achieve very low polarization ratios with all-dielectric beamsplitter coatings. The average intensity varia-tion is less than 0.5 % in the wavelength interval from 500 nm - 600 nm for all given design examples, for angles of incidence from 40 to 60o.
