Scattering-Type Polarizers Consisting of Fiber/Matrix and Methods to Enhance Polarization Property

摘要

A nonabsorbed-type polarizer consisting of aligned birefringent fiber/isotropic polymer composites was fabricated. By selecting a matrix polymer with the appropriate refractive index that was matched with the ordinary refractive index or extraordinary refractive index of the fiber, two different types of film were obtained. Both of these different types of film showed the polarization property due to the scattering and transmission depending on the polarization direction. Furthermore, taking advantage of these different optical characteristics between the two types of film, we fabricated an efficient polarizer by combining two films vertically, which was expected to achieve a high contrast ratio between two components of polarization light.
