Compositional and structural dependence of chromatic dispersion in tellurite hybrid microstructured optical fibers

摘要

The dependence of chromatic dispersion of tellurite microstructured optical fiber on composition and structure was investigated. The material dispersion is mainly dependent on material composition of core glass. And the waveguide dispersion of fiber mainly depends on refractive index distribution in cross-section. The radial step of refractive index produces a peak in waveguide dispersion curve whose value and position are related to both contrast of refractive index and its position. Based on this guidance, some particular dispersion profiles were designed in tellurite fibers.
