摘要: 在模式耦合理论的基础上，采用传统的波导轴线圆弧弯曲的方法，对TE01-TM11模式变换器的临界角进行了全面的优化分析。得出在临界角情况下，若考虑多模因素，则不能使TE01-TM11的能量发生全转换，而真正的最优化能量全转换角在临界角的附近，且转换的效率与弯波导曲率相关。Abstract: Based on the mode coupling theory, this paper analyzes the critical angle of the TE01—TM11 mode converter completely by traditional waveguide axis constant curvature. Energy converted from TE01 to TM11 mode by all under the critical angle with multimode factor is got. The actual optimum angle of energy complete conversion is in the neighborhood of critical angle, and conversion efficiency is related to the curvature of bent waveguide.
