## Abstract Oneβway light propagation through a steplike discontinuity of dielectricβslab waveguide is simulated by using the finiteβdifference beamβpropagation method (FDβBPM) and the Green's function method. The validity of the slowly varying envelope approximation in modeling of the total field
when the coupler returned to 20ΠC, showing that the effect is reversible with temperature. In summary, the proposed process permits the fabrication of couplers with polarization extinction similar to the fiber's. Moreover, this kind of device presents very low loss, and exhibits good mechanical and
