Electro induced birefringence
Webdouble refraction, also called birefringence, an optical property in which a single ray of unpolarized light entering an anisotropic medium is split into two rays, each traveling in a different direction. One ray (called the extraordinary ray) is bent, or refracted, at an angle as it travels through the medium; the other ray (called the ordinary ray) passes through the … WebSep 1, 2024 · In summary, based on density functional pseudo-potential plane wave method, we have calculated and presented energy band gaps refractive indices and the electro-optical coefficients of ZnS and CuAlS2 compounds. We used these values to study induced birefringence in the crystals by an applied electric field.
