Linear Birefringence Changes in Betaine Phosphite Crystal

Ultrahigh birefringence index-guiding photonic crystal fiber

We reported an ultrahigh birefringence PCF with a germanium-doped elliptical core, which is fabricated in our lab using the stack-and-draw method, and an ultrahigh birefringence of 1.1×10 is obtained experimentally via FBG and Sagnac loop.

Synthesis and crystal structure of cerium(IV) bis­(phosphite)

The structure of cerium(IV) bis-(phosphite), Ce(HPO3)2, has been solved by single-crystal X-ray diffraction and has trigonal (P-3m1) symmetry. The cerium(IV) cation exhibits site symmetry -3m. and is octa-hedrally coordinated by O atoms of the phosphite ligands (point group symmetry 3m.). The highly symmetrical compound has a layered structure parallel to the ab plane, and is closely related to...
