Abstract

The refractive index dispersion characteristics of CdF2-LiF-A1F3-PbF2 (CLAP) systems were measured by the minimum deviation method. The refractive index changes from 1.64 (at 0.3892 μm) to 1.54 (at 5.3036 μm). The material dispersion curve is relatively flat in the wavelength region from 1 μm to 3 μm. The zero material dispersion wavelength occurs near 1.9 μm)which is the longest value reported for the fluoride glasses. Postulating a step index single mode fiber and calculating a waveguide dispersion, the total dispersion was obtained for CLAP fibers. From the comparison of total dispersion curve for CLAP and a silica fiber, it is shown that the dispersion can be mutually compensated in the wavelength range from 1.32 μm to 2.0 μm.
