摘要
将铁电液晶作为缺陷层引入一维光子晶体中,基于液晶的电控双折射,形成快速窄带调谐滤波器。用传输矩阵法研究了铁电液晶缺陷光子晶体的可调谐滤波特性,计算了电场对滤波器透射峰的位置、强度、个数和带宽的影响,结果表明该滤波器呈现良好的滤波功能。
Base on electrically controlled birefringence of ferroelectric liquid crystal, onedimensional photonic crystals are infiltrated by ferroelectric liquid crystal defect films, which molecular director changed by electric field, the fast and narrow band tunable filter is proposed. The tunable filter property of photonic crystals is studied by the transfer matrix method. The effect of electric field on transmission spectrum peak wavelength, intensity, multi-channel and band wide is numerically calculated. The results show that the filter has good filtering.
