Paper Abstract

In this paper, we analyze and propose an exponentially modulated refractive index profile for large effective area fibers with non-zero dispersion characteristics. A linear finite element method is used for computing the modal propagation characteristics and modal field distributions of an optical fiber having an arbitrary refractive index profile. The core effective area and the dispersion characteristics are optimized by optimizing a constraint objective function in the profile parametric space. The optimum refractive index profile can give a core effective area of 110 micrometers 2. The dispersion varies linearly from 2.5 ps/nm-km to 4.5 ps/nm-km with a dispersion slope of 0.065 ps/nm2-km over 1.53 micrometers -1.56 micrometers wavelength range. Manufacturing tolerance analysis for the designed fiber characteristics is also studied. The bending loss for the fiber is around 0.003 dB/m for a bend radius of 100mm.
