| 摘 要： | 将标量时域有限差分法(FDTD)应用于弱导光器件的计算机仿真中，实现了标量时域有限差分法的理想匹配层(PML)边界条件．并对平行介质带定向耦合器进行了数值模拟和验证，所得结果与理论值非常一致。对平面光波导计算机辅助设计(CAD)将具有实际意义．可用于分析任意结构的弱导光器件。

| Abstract: | The scalar finite difference time domain (FDTD) method is used in the simulation of weakly guiding optical devices. The perfectly matched layer (PML) boundary condition for the scalar FDTD is implemented and verified by the simulation for the parallel slab directional coupler. It is shown that the result is in good agreement with the exact solutions. This method can be used as a powerful CAD tool in the analysis of weakly guiding optical devices. |
