We consider the operation principles of the sensor of an external electric field on the bases of microring resonators that consist of bent-strip waveguides with vertical or horizontal slots filled with nematic liquid crystal. The mode-field distribution and dispersion parameters of the bent-slot waveguides are calculated by using the algorithm based on the method of lines. The influence of the waveguide and microresonator structure (slot width, position and orientation, microresonator radius, etc.) on the sensor sensitivity is analyzed.
我们基于由带有垂直或水平狭缝且填充有向列型液晶的弯曲条形波导组成的微环谐振器，研究了外部电场传感器的工作原理。采用基于线方法的算法计算了弯曲狭缝波导的模场分布和色散参数。分析了波导和微谐振器结构（狭缝宽度、位置和方向、微谐振器半径等）对传感器灵敏度的影响。
