【 摘 要 】

The influence of magnetic field on the reflection spectra of one-dimensional magneto-photonic crystals of two types has been investigated. The first type is a periodically layered defect-free magnetic-dielectric structure, the second one is a magnetically active defect placed between dielectric photonic crystal mirrors. If the frequency of magnetic resonance is close to the central frequency of one of the photonic band gaps or to the frequency of the defect mode, it creates a significant reconstruction of the spectrum in the mentioned frequency domain. Namely, it can bring the suppression of the oscillation spectrum and the defect mode, which makes it possible to effectively control the spectrum of such a structure by an external magnetic field.
