## Abstract One‐way light propagation through a steplike discontinuity of dielectric‐slab waveguide is simulated by using the finite‐difference beam‐propagation method (FD‐BPM) 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 20ЊC, 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
