Intrinsic losses in mixed silver halide fibers

The intrinsic loss processes in mixed silver halide fibers and their dependence on the halide concentration are studies in this work. This includes the electronic band-gap absorption, multiphonon absorption, and Rayleigh scattering. In addition, we study the halide concentration dependence of the refractive index and the static dielectric constant in silver halide mixtures. As a result, we obtain numerical values for the predicted minimum loss, the wavelength of minimum loss, and the optical window of the mixtures as a function of the halide concentration in the fiber.
