利用染料掺杂的双折射液晶作为周期性结构中的缺陷层，已经证明了一维周期性结构中缺陷模激光波长的电调谐。在施加电场时，激光波长被广泛地调谐，这是由于由场诱导的液晶分子的重新排列引起的缺陷层中的折射率变化。
ABSTRACT Electrical tuning of a wavelength of a defect mode lasing in a one-dimensional periodic structure has been demonstrated using a dye-doped nematic liquid crystal as a defect layer in the periodic structure. Lasing wavelength is widely tuned 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.
