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 μm^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 μm 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. © 2001 John Wiley & Sons, Inc.
