Transmission spectra of a photonic crystal resonator structure have been obtained where the Bragg dielectric mirrors contain a finite number of periods with an inverted order of layers and the resonator layer is made of a ferroelectric with a permittivity many times exceeding the permittivity of the layers in Bragg mirrors. Almost a complete transmission suppression was detected not only in the photonic band gap (except for a narrow region of the defect mode), but also outside the forbidden band. •The resonator layer is made of a ferroelectric with permittivity much more than Bragg mirrors.•Almost complete transmission suppression is observed not only in the photonic band gap, but also outside the forbidden band.•An effective rearrangement of the transmission spectrum and control of the position of the transmission peak is shown.
