Abstract
The present invention is directed to silver halide fibers. In one embodiment, the fiber has been doped with AgI or a metal compound of the formula MY wherein M is selected from Li, Na, K, Rb, Cr, Mg, Ca, St, Ba, Cd or Hg, and Y is selected from Cl, Br, or I. The fiber has large, elongated grain core structure and decreased infrared transmission losses and a more even/cladding interface in cladded embodiments.
