在液晶渗透的合成蛋白石薄膜中，证明了反射光谱中的光阻带的电场调谐。蛋白石的反射峰在施加电场时发生位移，这是基于施加电场时分子重新取向引起的折射率变化。研究了阻带位移的动态响应，发现其响应速度快到微秒级。(C)2001年美国物理学会。
Electric field tuning of an optical stop band in a reflection spectrum is demonstrated in a synthetic opal thin film infiltrated with liquid crystal. The reflection peak of the opal shifts upon the application of the electric field, and this is based on the refractive index change caused by molecular reorientation upon application of a field. The dynamic response of the stop band shift was also studied, and fast response of the order of microsecond was observed. (C) 2001 American Institute of Physics.
