Abstract :
Temperature-dependent Sellmeier coefficients are necessary to optimize optical design parameters of the optical fiber transmission system. These coefficients are calculated for fused silica (SiO2 ), aluminosilicate, and Vycor glasses for the first time to find the temperature dependence of chromatic dispersion at any wavelength from UV to 1.7 μm. The zero dispersion wavelength λ0 (1.273 μm for SiO2, 1.393 μm for aluminosilicate, and 1.265 μm for Vycor glasses at 26°C) varies linearly with temperature, and dλ0/dT is 0.03 nm/K for aluminosilicate and Vycor glasses, whereas for SiO2 it is 0.025 nm/K. This study interprets the recently observed experimental value of dλ0/dT for two dispersion shifted optical fibers; and the dominantly material origin of dλ0/dT is confirmed here as a fundamental property of the optical fiber glasses
