Birefringence refractive index
Birefringence is the optical property of a material having a refractive index that depends on the polarization and propagation direction of light. These optically anisotropic materials are said to be birefringent (or birefractive). The birefringence is often quantified as the maximum difference between refractive … See more A mathematical description of wave propagation in a birefringent medium is presented below. Following is a qualitative explanation of the phenomenon. Uniaxial materials The simplest type … See more While the best known source of birefringence is the entrance of light into an anisotropic crystal, it can result in otherwise optically isotropic materials in a few ways: See more Birefringence and other polarization-based optical effects (such as optical rotation and linear or circular dichroism) can be observed by measuring any change in the polarization of light passing through the material. These measurements are known as See more In an isotropic medium (including free space) the so-called electric displacement (D) is just proportional to the electric field (E) according to D … See more Much of the work involving polarization preceded the understanding of light as a transverse electromagnetic wave, and this has affected some terminology in use. Isotropic materials have symmetry in all directions and the refractive index is the same for any … See more The best characterized birefringent materials are crystals. Due to their specific crystal structures their refractive indices are well defined. … See more Birefringence is used in many optical devices. Liquid-crystal displays, the most common sort of flat-panel display, cause their pixels to become lighter or darker through rotation of … See more WebHence, the refractive index sensitivity has been established up to 2375.8 dB/RIU in the narrow RI range (1.333–1.341 RIU) and temperature sensitivities up to 1.1 dBm/°C in the …

WebIt was shown that the geometrical birefringence increases substantially in proportion to the refractive-index difference A (refer to Fig. 3.33). In silicon-on-insulator (SOI) waveguides, the refractive-index difference becomes of the order of Δ = [1 – ( n 0 / n 1 ) 2 ] /2 = 0.41, where n 1 (= 3.48) and n 0 (= 1.444) are refractive indices of ...
