摘要
将补偿算符吸收边界条件应用到光束传输方法 (BPM ) ,计算了高斯脉冲在平面波导中的传输模场 ,并与透明边界条件 (TBC)的BPM计算值以及理论值进行了比较。结果发现 ,补偿算符吸收边界条件能够有效地抑制边界的反射 。
The complementary operators method(COM) is applied to the beam propagation method(BPM) and is compared with the transparent boundary condition while dealing with the problem of gauss pulse propagating in planar waveguide. It’s found that COM is much effectual for decreasing the reflection of the artificial boundary.
