在一维光子晶体中，利用导电聚合物作为主动发射层和向列液晶作为可电调谐缺陷层，证明了缺陷模激光波长的电调谐。在电场作用下，激光波长被广泛调谐，这是由于液晶分子的场致排列引起向列液晶缺陷层的折射率变化而引起的缺陷模移位。(C) 2004年美国物理研究所。
Electrical tuning of the wavelength of the defect mode lasing in a one-dimensional photonic crystal has been demonstrated using a conducting polymer as an active emission layer and a nematic liquid crystal as an electrically tunable defect layer in the periodic structure. Lasing wavelength is widely tuned upon applying the electric field, which follows a defect mode shift due to the refractive index change in the nematic liquid crystal defect layer caused by field-induced realignment of the liquid crystal molecules.
