We present the simulated distribution of the local director of nematic liquid crystal (NLC) which is confined inside cylindrical macropores of the porous silicon. The Frank free energy approach is used to describe the NLC in porous medium. The influence of molecular anchoring strength and external electric field applied is investigated. Bruggeman approximation is used while calculating effective refractive index of each layer in porous silicon multilayer structure. Reflectivity spectrum of the latter is simulated using transfer matrix approach. Electrical tuning range of microcavity designed for resonance at 1330 nm vary from 8.5 nm up to 16 nm for weak and strong surface anchoring conditions respectively.
