Analysis of guided modes of a rib optical waveguide with trapezoidal cross section
In this paper we present a method of separation of variables in evaluating propagation constants and field distributions of gulden modes in a rib waveguide with trapezoidel cross section. The formulas are simple in form and easy to apply. Calculated results done with pocket calculator agree well with that of exact numerical analysis.
