Abstract :
A numerical method for calculating the cutoff frequencies in W -type single-mode fibers, which is based on the Chebyshev power-series approach, is discussed. It is shown that the method is fast and accurate, and can be applied to arbitrary-core-profile W-type fibers. Calculated results are presented to show the accuracy and convergence of the method. The method can be applied to discrete numerical data obtained from index profile measurements
