Paper Abstract

Four wave mixing and supercontinuum from tellurite photonic crystal fibers have been widely researched. Their efficiencies depend largely on fiber nonlinearity and chromatic dispersion. We have shown that the composite microstructured optical fibers (CMOFs) can have high flexibility on chromatic dispersion control when refractive index difference between core and cladding becomes larger. Cladding materials with much lower refractive index than tellurite glass are required. We report here a novel tellurite core-phosphate cladding CMOF. Phosphate glasses which thermal expansion coefficient, viscosity, glass transition temperature, deformation and crystallization temperature are close to those of tellurite 78TeO2 - 5ZnO - 12Li2O - 5Bi2O3 (mol%) (TZLB) glass are systematically investigated. The phosphate glass we developed has high transparency and a broad transmission region up to 3 μm as well as a notably low refractive index. Using the phosphate glass doped with mixed alkali oxides obtained in this work, the refractive index difference between core and cladding becomes as high as 0.5 which is sufficiently high to control the chromatic dispersion with high freedom. Our work shows that tellurite-phosphate CMOFs are promising candidates as highly nonlinear fibers with freely controlled chromatic dispersion for nonlinear applications.
