当向列相液晶的长分子轴平行于球体表面取向时，由向列相液晶嵌入紧密堆积的二氧化硅球体（合成多孔蛋白石）的空隙空间制成的光子晶体表现出显着的电场诱导光学布拉格反射峰位移。当长轴方向垂直于球体表面时，没有观察到这种效应。
Photonic crystals made of nematic liquid crystal intercalated into the void space of close-packed silica spheres (synthetic porous opal) exhibit significant electric-field-induced shift of the optical Bragg reflection peak when the liquid crystal has the long molecular axis oriented parallel to the sphere surfaces. No such effect is observed for comparable fields when the long-axis orientation is normal to the sphere surfaces.
