One-dimensional tunable photonic crystals with spin crossover material for the terahertz range.

Mounaix, P.; Freysz, E.; Degert, J. etc., Applied Physics Letters, 89 [17] 174105 (2006)

The authors use a spin crossover material as a defect inserted into a periodic structure of alternating layers of glass and air. A single defect mode of this Bragg filter designed for the submillimeter wavelength can be tuned over 15 GHz by inducing the spin transition of the defect. This shows potential applications of spin crossover materials at terahertz frequencies.
