Birefringence applications
WebBirefringence is the phenomenon exhibited by certain materials in which an incident ray of light is split into two rays, called an ordinary ray and an extraordinary ray, which are plane- (linear) polarized in mutually orthogonal planes, or circular-polarized in opposite directions (left and right). From: Lasers for Medical Applications, 2013. Web1 day ago · Birefringence can be affected by a number of factors such as bond orientation [79] strain [80], and polarizability [81]. The inversion of the birefringence was intimately related to the smaller Mn-O bond length in comparison to Zn-O along the c direction [82] i.e. smaller dipole moment (p → = l → q). A smaller bond length in the [0001 ...

FDTD simulation is used to investigate the effect of ellipticity on birefringence in a hexagonal photonic crystal fiber having elliptical air holes with Kerr nonlinearity without defect. It is found that birefringence property in hexagonal structure PCF depends on structural configuration, where ellipticity plays a vital role.
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 the polarization (circular birefringence) of linearly polarized light as viewed through a sheet polarizer at the screen's surface. … See more Birefringence is the optical property of a material having a refractive index that depends on the polarization and propagation direction of light.
