A bulk electro-optic (EO) modulator based on the ultrahigh-order guided modes, which are excited in a symmetrical metal-cladding waveguide (SMCW), has been exploited. This kind of mode in a SMCW has high sensitivity to phase shift by changing the refractive index of the guiding layer. Compared with phase modulation via the bulk EO modulator without a waveguide, the applied half-wave voltage is reduced for one magnitude. This work may have practical applications in optical information processes.
一种基于在对称金属包覆波导（SMCW）中激发的超高阶导模的体电光（EO）调制器已被开发出来。SMCW中的这种模式通过改变波导层的折射率对相移具有高灵敏度。与没有波导的体EO调制器的相位调制相比，施加的半波电压降低了一个数量级。这项工作可能在光信息处理中有实际应用。
