Abstract :
In this paper, the Bragg mirrors manufactured of the macroporous silicon infiltrated with liquid crystals are investigated. The reflectance spectrum of the structure is calculated using a transfer matrix method. The influence of the applied alternating field on reflectance spectrum of the structure is considered. The comparative analysis of the Bragg lattices reflectance spectra with different anisotropy of liquid crystals is realized when the voltage is applied. The opportunity of combination of the porous silicon layers infiltrated with positive or negative anisotropy of the liquid crystals is discussed
