WebApr 19, 2011 · Abstract: An optical fiber twist sensor is proposed by using solid core low birefringence photonic crystal fiber (LB-PCF)-based Sagnac interferometer. The twist effects on the fiber are theoretically analyzed. The results show that the dip wavelength of the transmission spectrum shifts with the twist angle with a high sensitivity and resolution … WebThe birefringence change is reduced by 65% in the NLC doped with 25% reactive monomer, which is polymerized close to the nematic-to-isotropic phase transition. This technique could be used in liquid crystal devices where the birefringence change is unfavored. ...

WebThe refractive index of each of the four common silicon carbide polytypes has been measured over the visible range. The data were analyzed in an attempt to relate the birefringence to the relative hexagonal character of the polytype. A general relationship exists, namely, that the birefringence increases with increasing hexagonal character of … WebMar 9, 2024 · In this work, an elimination method of the temperature-induced linear birefringence (TILB) in a stray current sensor is proposed using the cylindrical spiral fiber (CSF), which produces a large amount of circular birefringence to eliminate the TILB based on geometric rotation effect. First, the differential equations that indicate the polarization … WebThe term birefringence is sometimes also used as a quantity (see below), usually defined as the difference between extraordinary and ordinary refractive index at a certain optical … The refractive index of a material depends on the optical frequency or wavelength; … The mentioned problem can be fixed by using a polarization-maintaining fiber, … where A(z) is the complex amplitude of the light field at position z..
