Some results from a modal analysis of a rib waveguide by using a hybrid finite-element method are described. It is shown that the approximate formulas derived by using the method considered by E. A. J. Marcatili are quite accurate when the fields are closely confined to the waveguide. The emission patterns of a GaAs rib-waveguide laser, predicted from the modal solution, are presented.
