Abstract
The optical characteristics of the asymmetric metal-clad waveguide are analysed, more accurate formulae are derived for calculating the propagation constants and loss coefficients of TE and TM modes. The computed results for Al/GaAs/AlGaAs waveguides are in good agreement with the numerical results, and are much more accurate than the results in some other papers. The method for selecting the TE0 mode is presented and discussed.
