High Birefringent Liquid Crystals

Molecular Crystals and Liquid Crystals Science and Technology. Section A. Molecular Crystals and Liquid Crystals, 1995
Abstract Several liquid crystal dyes and fluorinated compounds with high birefringence are synthesized and their properties evaluated. These polar compounds are useful dopants for enhancing the dielectric anisotropy of the dialkyl diphenyl-diacetylene host.

Photonic bandgap fibers with high birefringence

IEEE Photonics Technology Letters, 2002
A highly birefringent air-guiding photonic crystal fiber which provides guidance by a full two-dimensional photonic bandgap (PBG) effect is proposed. The fiber core is formed by introducing a large air hole that has an area of four unit cells of the cladding materials.

Precise method for modifying birefringence of stress-induced high-birefringence fiber

Optics Letters, 2010
A precise method for modifying the birefringence of stress-induced high-birefringence (Hi-Bi) fiber is demonstrated by side polishing a Panda-type fiber with a maximum polished length of at least 14 cm. The polishing depth is controlled with an accuracy of 0.1 microm by piezoelectric ceramic microdisplacement.

Photoinduced birefringence in optical fibers: a comparative study of low-birefringence and high-birefringence fibers

Optics Letters, 1992
A 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 ...

New Nematics with High Birefringence

Molecular Crystals and Liquid Crystals Science and Technology. Section A. Molecular Crystals and Liquid Crystals, 1995
Abstract We prepared new compounds with the hexendiyne unit as central bridging group. The substances are nematic, with clearing temperatures much higher than those of other two ring compounds. They show the highest birefringence ever observed in liquid crystals, modest viscosities and medium dielectric anisotropy. Their stability in low polar mixtures
