Tunable photonic crystals controlled by spin-crossover material in Terahertz range

Abstract : We use a spin crossover material as active defect inserted into a periodic structure of alternating layers of glass and air. By inducing the spin transition of the defect, a single defect mode of this Bragg filter designed for the submillimeter wavelength can be tuned over 15 GHz. This shows prospective applications of spin crossover materials at terahertz frequencies.
