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.
Claims9
An unclad optical fiber comprising a silver halide solid solution of the formula AgCl.sub.x Br.sub.1-x wherein x ranges from 0 to 1.0, and one or more dopants selected from the group consisting of AgI and those of the formula MY, wherein M may be Li, Na, K, Rb, Cr, Mg, Ca, Sr, Ba, Cd or Hg, and Y may be Cl, Br or I.
An optical silver halide fiber exhibiting polycrystalline, essentially void--and microcrack free texture whereby the grain size decreases from the center of the core towards the periphery and the grains are ellipsoidally shaped and oriented with their longitudinal direction parallel to the fiber axes.
A optical fiber, comprising a silver halide solid solution of the formula AgCl.sub.x Br.sub.1-x wherein x ranges from 0 to 1.0, and one or more dopants selected from the group consisting of AgI and those of the formula MY, wherein M may be Li, Na, K, Rb, Cr, Mg, Ca, Sr, Ba, Cd or Hg, and Y may be Cl, Br or I and wherein said fiber has a core coated with a polymer having a lower refractive index than said core.
An optical fiber comprising a silver halide solid solution of the formula AgCl.sub.x Br.sub.1-x wherein x ranges from 0 to 1.0, and one or more dopants selected from the group consisting of AgI and those of the formula MY, wherein M may be Li, Na, K, Rb, Cr, Mg, Ca, Sr, Ba, Cd or Hg, and Y may be Cl, Br or I, wherein said fiber is clad with a lower refractive index silver halide cladding material of the formula Ag Cl.sub.z Br.sub.1-z wherein z is from 0 to 1.0.
