| 摘 要： | 本文从通常WKB方法本身的缺陷出发,提出了一种能够在一定程度上修改通常wKB方法,并且求解精度高的方法。该方法在处理任意折射率分布的波导问题时,非常有效,简明且适用。该方法较通常WKB方法精度高。

| Abstract: | we present an analytical formula for planar waveguides with truncated index profiles. This analytical formula is a correction to the general WKB method and results of high accuracy are obtained. This method can be extended to arbitrary graded-index planar waveguides. |
