|Abstract:||In this paper, we analyze and propose an optimum index profile which can give a larger core effective area with nonzero-dispersion characteristics. The index profile is modeled by an exponentially modulated linear chirp profile function. A linear finite-element method (LFEM) is used for computing the transmission characteristics of an optical fiber having an arbitrary refractive-index profile. The optimum index profile can give a core effective area of 117 mum(2). The dispersion varies linearly from 2.5 to 4.5 ps / nm . km with a dispersion slope of 0.065 ps / nm(2) . km over the 1.53-1.56 mum wavelength range. Sensitivity analysis for the designed fiber characteristics is also studied. The bend loss is about 0.001 dB / m for a bend radius of 100 mm. (C) 2001 , Inc.|
