The mode dispersion of trapezoidal cross‐section narrow ridge dielectric optical waveguides is calculated by the Weighted Residual Method (WRM). In the sloping region, the field is expressed in terms of Airy functions, thus having no arbitrariness at the boundaries. The result is compared with previously reported experimental and theoretical results. Agreement between the experimental and the predicted results is good. © 1996 John Wiley & Sons, Inc.
