Dispersion and Modal Behavior of Different Optical Fiber Materials

Temperature dependent Sellmeier coefficients are necessary for determining different optical design parameters which are important for optical fiber communication system. These coefficients are calculated for fused Silica (SiO2), Aluminosilicate and Vycor glasses, to find the dependence of chromatic dispersion on temperature and at any wavelengths encompassing the profile dispersion parameter. The zero-dispersion wavelengths, for single mode fiber is modeled and investigated for all three materials, considering step-index fiber model. Temperature effects on zero-dispersion wavelengths, are also investigated for a wide range (-1200C to 1200C) as well as including the relative refractive index difference. The two important modal properties, the effective area and power propagation through the fiber are calculated first solely and then considering the perfectly matched layer (PML).
