Birefringence in optics
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 See more Birefringence and other polarization-based optical effects (such as optical rotation and linear or circular dichroism) can be observed by … See more Birefringence is used in many optical devices. Liquid-crystal displays, the most common sort of flat-panel display, cause their pixels to … 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 … See more The best characterized birefringent materials are crystals. Due to their specific crystal structures their refractive indices are well defined. Depending on the symmetry of a crystal structure (as determined by one of the 32 possible crystallographic point groups 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 = ɛE where the material's permittivity ε is just a scalar (and equal to n ε0 where n is the index of refraction). … See more WebBirefringence can occur only in optically non-isotropic materials. Often, it results from non-cubic lattice structures of optical crystals, i.e., an intrinsic anisotropy.. In other cases, birefringence can be induced in originally …

Webthe relationship is linear, birefringence magnitude can be substituted for actual stress (i.e. high birefringence = high residual stress). Many factors contribute to birefringence in optical materials. For example, any of the following conditions can cause stress birefringence: applied external pressure (from mounting hardware, etc.); primary ... WebMar 31, 2016 · View Full Report Card.

WebA study of photoinduced birefringence in bow-tie (stress-induced) high-birefringence (Hi-Bi) and low-birefringence (Lo-Bi) germanosilicate optical fibers is conducted by using 532-nm light. The study reveals that Hi-Bi fibers are insensitive to light polarized along the fast axis, in contrast to Lo-Bi fibers, which are photosensitive along both axes. WebThis birefringence was considered in Menyuk’s formulation [33] which describes the optical propagation in an elliptical birefringent medium with birefringent ellipticity angle θ. When a weakly linear birefringent fiber is twisted to obtain θ = 35 ° [34], the NPR effect is canceled [35], and the nonlinear polarization rotation is voided.
WebWe describe a technique for the measurement of the birefringence spatial distribution in a single-mode optical fiber with a resolution of 1 m. This technique is based on a polarization optical time-domain reflectometer using a rotary linear polarizer. We report results performed on different types of fibers: standard step-index and dispersion shifted … WebAs birefringence increases, the colors repeat (see figure below), but get more and more pastel (washed out). To describe interference colors we must specify both a hue and an order (e.g., 2nd order red; see chart below). Minerals with low birefringence show only white, gray and black interference colors.
WebIn a bent optical fiber, lateral internal stress induces a birefringence, βb. At λ = 0.633 μm in a silica fiber, βb = 7.7 × 107r2/R2 deg/m, where r is the fiber radius and R is the bending radius.
