论文摘要
通过理论和数值分析研究了由平行板波导模式与非线性半细条晶体晶体之间的耦合引起的光学双重性。在这样的系统中，波导通道与血清文学微孔子的窃窃库模式相耦合，以确保在几个MW/CM2的输入强度下可确保行为的行为。可以通过改变金属层的厚度来控制系统的特征最小切换时间（大约30 ps），该金属层的厚度将波导和耳语画廊模式融合在一起。这是由质量Q因子的变化以及谐振器的耦合系数的条件。该系统的主要优点是制造简单性，3微米的小尺寸，以及通过利用电流效应来调整过程的可能性。
The optical bistability caused by the coupling between modes of the parallel-plate waveguide and a nonlinear hemicylindrical crystal is studied using theoretical and numerical analysis. In such a system a waveguide channel is parallelly coupled to whispering gallery modes of a hemicylindrical microresonator ensuring bistable behaviour at input intensities of the order of a few MW/cm2. The characteristic minimum switching time of the system (around 30 ps) can be controlled by varying the thickness of the metal layer which couples the waveguide and whispering gallery modes. This is conditioned by the change of the quality Q-factor, as well as the coupling coefficient of the resonator. The main advantages of the system are fabrication simplicity, small sizes of the order of 3 microns and the possibility of adjusting the processes by making use of the electro-optical effect.
