Annotation	We review recent results of both experimental and theoretical work aimed at developing tunable devices with optical properties in the THz range controllable by an external parameter. The presented devices include a semiconductor platelet, strontium titanate based elements and one-dimensional photonic crystals with defects. We show that it is possible to strongly modulate the complex permittivity in the THz range by light illumination, temperature and voltage.
