Abstract
Theoretical and experimental results for waveguide modes with a distin ctive channel waveguide switching geometry are presented from the view point of improving the switching contrast for hybrid-mode propagation. The channel waveguide structure consists of two types of active mater ial covering regions of a nematic liquid crystal; one has a pair of st rip electrodes, and the other is without electrodes. An experimental s witch is demonstrated to have the contrast ratio of 1430 for the hybri d modes with E1n(y) primary components.
