摘　　要：脊波导的截止波长与脊位置密切相关,其值可通过脊位置的改变而改变.这里将用有限差分法分析不对称脊波导脊位于不同位置时主模的截止波长.并给出了一些图示.The cutoff wavelength of ridge waveguide is very closed to the ridge position. It can be changed by changing the ridge position. The influence of the ridge position on the cutoff wavelength of the dominant mode in asymmetric single ridge waveguide is analyzed by finite difference method. And some figures are presented.
