Аннотация: The photonic crystal (PC) nanostructures with magnetic layer of gradient thickness for tunable inverse Faraday effect (IFE) are proposed. In this nanostructure one can observe an optical photonic crystal defect mode, when the sharp resonance peak appears in the bandgap of the transmittance spectrum. This peak is accompanied by the strong localization of light in the magnetic layer. So, the dramatic enhancement of the IFE can be observed. The spectral position and amplitude of this peak depends on the thickness of the magnetic layer, h. Two designs of magnetic PC nanostructures are discussed. The first design has smooth magnetic layer with thickness gradient that allows to tune the spectral position of peak in transmittance spectra and the IFE gradually. The second design has perforated magnetic layer and provide spatially localized emergence of the IFE in the spots of several microns.
