We present device designs in macroporous silicon photonic crystals based on the infiltration of individual pores with liquid crystals which yield actively tunable photonic devices. These designs have been developed via a photonic Wannier function approach that allows the characterization of such devices via complex transmittance and reflectance coefficients. As a result, individual devices may be represented by small frequency-dependent scattering matrices. In turn, these scattering matrices form the basis of a quantitative circuit theory that allows to design complex functional elements that are very hard to handle with other simulation techniques.
