Filled liquid crystal depolarizers

Abstract

The construction and properties of scattering type liquid crystal depolarizers are discussed. The Mueller matrices that describe these devices are measured and compared to ideal depolarizers and ideal linear materials. The present depolarizers do not perform as well as crystal pseudodepolarizers. Nevertheless, when polarized light is incident on one of these devices the polarization of the transmitted light can be uniform to within 5%. These devices have the advantage that they can be made to areas as large as 30-30 cm or larger, are inexpensive, and can be electrically switched off and on.

Broadband loss-less optical thin-film depolarizing devices

“…Thick anisotropic substrates have formerly provided solutions to depolarize light [21,[37][38][39][40][41][42][43]. The technique consists in using a bulk material with a similar cutting edge κ (see Fig.…”

Monochromatic Depolarizer Based on Liquid Crystal

“…It is made by using scattering properties or a spatially distributed birefringence of the used LC based materials. Scattering properties of silica nanoparticles in LCs matrix [10] and cholesteric LCs in a wedge configuration [11] were presented as effective depolarizers. Spatial distribution of birefringence in LCs' polymers and different processes of LCs' polymer alignment layers were shown, as well.…”

“…However, a polarized light source is sometimes highly undesirable in a certain optical system, including an optical communication system, an interferometer, and sensors [6], [7]. Therefore, the management of polarization anisotropy is critical to achieve light source with desired properties.…”
