从提高混合模传输的开关对比度的角度，给出了具有独特的通道波导开关几何形状的波导模式的理论和实验结果。通道波导结构由两种类型的活性材料覆盖的液晶区域;一个有一对条形电极，另一个是没有电极。实验结果表明，对于E（1 n）（y）主分量的混合模式，开关的对比度为1430。
Theoretical and experimental results for waveguide modes with a distinctive channel waveguide switching geometry are presented from the viewpoint of improving the switching contrast for hybrid-mode propagation. The channel waveguide structure consists of two types of active material covering regions of a nematic liquid crystal; one has a pair of strip electrodes, and the other is without electrodes. An experimental switch is demonstrated to have the contrast ratio of 1430 for the hybrid modes with E(1n)(y) primary components.
