Abstract
A new beam propagation method (BPM) based on the expansion of a global basi s function is introduced for the numerical simulation of field propagation in optical waveguides. In dealing with the boundary truncation problem, tan gent-type variable transformation is applied. To show the validity and usef ulness of this approach, numerical results are shown for guided-mode propag ation in a straight slab waveguide and TE-wave propagation through a tapere d slab waveguide.
