Light transmission spectrum of a multilayer photonic crystal with a central liquid-crystal defect layer placed between crossed polarizers has been studied. Transmittance was varied due to the magnetically induced reorientation of the nematic director from homeotropic to planar alignment. Two notable effects were observed for this scheme: the spectral shift of defect modes corresponding to the extraordinary light wave and its superposition with the ordinary one. As a result, the optical cell allows controlling the intensity of interfering defect modes by applied magnetic field.
研究了一种多层光子晶体的光透射光谱，该光子晶体具有置于交叉偏振器之间的中心液晶缺陷层。由于磁诱导向列指向矢从垂直排列重新取向为平面排列，透射率发生了变化。对于该方案观察到了两个显著效应：对应于异常光波的缺陷模式的光谱移位及其与寻常光波的叠加。结果，该光学单元允许通过施加磁场来控制干涉缺陷模式的强度。
