Abstract: Liquid crystal infiltration is becoming an important tool to control the optical properties of complex dielectric systems like photonic crystals and disordered dielectrics. We discuss the technical aspects of liquid crystal infiltration in meso-porous structures, give some details of the sample preparation process, and discuss possibilities for tuning the optical properties of both ordered and disordered systems.
