TLDR
In this paper, a new polarization splitter which utilizes artificial anisotropic dielectrics is presented, which is composed of layers of periodically laminated SiO2/TiO2 thin films.Abstract:
Experimental verification is made of a new polarization splitter which utilizes artificial anisotropic dielectrics. The splitter is composed of layers of periodically laminated SiO2/TiO2 thin films. The SiO2 and TiO2 films are alternately deposited by rf sputtering and reactive dc sputtering, respectively. The thickness of each layer is 50 nm, while the total number of the layers amounts to 2000. The measured polarization split angles are 5.7° (λ=0.63 μm) and 5.1° (λ=1.3 μm), being roughly the same as those predicted.read more

Design considerations of form birefringent microstructures
TL;DR: It is shown that although the reflection characteristics can be accurately modeled with the second-order EMT, the phase difference created by form birefringence for TE- and TM-polarized waves requires the use of a more rigorous, RCWA approach.

TL;DR: In this article, an optical element that is transparent for TM polarization and reflective for TE polarization at an arbitrary incidence angle and operational wavelength was designed, and the experiments with the fabricated element demonstrate a high efficiency (97), with polarization extinction ratios higher than 220:1 at a wavelength of 1.523 m over a 20 angular bandwidth by means of the ASR characteristics of the device.

TL;DR: The characteristics of the polarizer composed of periodically laminated a-Si/SiO(2) layers are calculated and it is found that the split angle between the ordinary wave and the extraordinary wave in the polarizers is more than three times larger than that in well-known birefringent crystals.
