Abstract
A scalar Rayleigh-Ritz method using rational functions as an orthonorm al basis is presented. This formalism is especially useful for the cal culation of the fundamental eigenmode of optical waveguides near cutof f. An application for the optimum design of the large-spot output wave guide in tapered spot-size transformers is described.
