利用向列相液晶作为一维周期结构中的缺陷层，实现了一维周期结构中缺陷模的电调谐。当施加电场时，缺陷模的波长发生移动，这是由于场诱导液晶分子重新排列引起缺陷层的折射率变化所致。利用简单的传递矩阵进行了理论计算，计算结果与实验结果吻合较好。
Electrical tuning of defect modes in a one-dimensional periodic structure has been demonstrated using a nematic liquid crystal as a defect layer in the periodic structure. The wavelength of the defect mode shifts upon applying the electric field, which is due to the refractive index change in the defect layer caused by the field-induced realignment of the liquid crystal molecules. The theoretical calculation based on a simple transfer matrix has been carried out, and the result has been found to agree with the experimental result.
