We report a reversible refractive index change of a silicon nitride film deposited by plasma-enhanced chemical vapor deposition. The reversible change was observed in alternately processing of annealing and ultraviolet irradiation. The reversible index change has a potential to be applicable to non-volatile photon-ic interference circuits.
