Modal structure of an MCVD optical waveguide fiber

In this paper we compare modal analyses of a Modified Chemical Vapor Deposition (MCVD) optical waveguide fiber and an idealized fiber. The pertinent profile parameters of the idealized fiber are obtained from the MCVD profile. We have validated the concept of an optimum α developed in our previous work. The reduction of the bandwidth of the MCVD fiber is shown to be directly related to the imperfections in the profile inherent in the MCVD manufacturing process.
