迄今为止,还没有关于山字形脊波导的研究报道。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,本文用有限差分法计算了山字形脊波导主模的截止波长,并给出了脊位于不同位置时的详细数据,这些数据对设计山字形脊波导具有重要参考价值,为脊波导器件的小型化提供有力指导,对工程应用具有重要的参考价值。
So far, there is no report about the ridge ridge waveguide. The cutoff wavelength of the ridge waveguide is closely related to the ridge position, and its value can be changed by changing the ridge position. In this paper, the cutoff wavelength of the main mode of the ridge ridge waveguide is calculated by the finite difference method, and the detail of the ridge at different positions is given Data. These data have important reference value for the design of ridge-shaped ridges and waveguides. They provide powerful guidance for miniaturization of ridge-waveguide devices and have important reference value for engineering application.
