| Abstract: | 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. |
