在平面和垂面锚定条件下，研究了两种填充液晶的实芯光子晶体光纤中的可切换波导。解决实验使用交流电压显示偏振相关和独立的响应时间下降到几毫秒的影响。它表明，两个液晶填充的光子晶体光纤的衰减光谱可以显着改变，只是通过改变边界条件。电磁场模拟，这是与实验结果吻合得很好。
Switchable waveguiding is investigated in two liquid-crystal-filled photonic crystal fibers with a solid core using the nematic liquid-crystal mixture E7 under planar and homeotropic anchoring conditions. Addressing experiments using ac voltages show polarization-dependent and -independent effects with response times down to a few ms. It is shown that the attenuation spectra of the two liquid-crystal-filled photonic crystal fibers can be changed dramatically by just varying the boundary conditions. Electromagnetic field simulations are presented, which are in good agreement with the experimental findings.
