We present a theoretical study of the dispersion and energy properties of the eigenwaves (TEand TM-modes) in a four-layer structure composed of a magneto-optical yttrium iron garnet guiding layer on a dielectric substrate covered by a planar nanocomposite guiding multilayer. The bigyrotropic properties of yttrium-iron garnet are taken into account for obtaining the dispersion equation and an original algorithm for the guided modes identification is proposed. We demonstrated the polarization switching of TE-and TM-modes dependent on the geometrical parameters of the guiding layers. The dispersion diagrams and field profiles are used to illustrate the change of propagation properties with variation of the multilayer thickness ratio of the nanocomposite's layers. The energy flux distributions across the structure are calculated and the conditions of the optimal guiding regime are obtained. The power switching ratio in the waveguide layers of about 6 dB for the wavelength range of 100 nm is shown to be achieved.

“…Detailed consideration of transverse magneto-optical Kerr effect and the role of asymmetry of claddings of single magnetic film is presented in [34]. Experimental studies of the transverse magnetooptical Kerr effect for waveguide modes of PC's with a microresonator layer have been performed recently and the resonant effect enhancement was demonstrated for the modes excitations [35]. Another consequence of the asymmetry is the difference in the signs of δ in the magneto-optical modes "2-8" in the structures of the type I and II (Figure 3 (b,c)).…”

Abstract. We present the study of the waveguide modes of one-dimensional magnetic photonic crystals with in-plane-magnetized layers. There is a magneto-optical effect of nonreciprocity for the TM-modes propagating along the layers perpendicularly to the magnetization. Due to the non-reciprocity the phase velocity of the modes changes with magnetization reversal. Comparison of the effect in the non-magnetic photonic crystal with additional magnetic layer on top and a magnetophotonic crystal with altering magnetic layers shows that the effect is greater in the first case due to the higher asymmetry of the claddings of the magnetic layer. This effect is important for the light modulation with external magnetic field in waveguide structures and may be used for design of novel types of the magneto-optical devices, sensors of magnetic field or biosensors.

“…Gazzano et al [13] experimentally showed the possibility of implementation of a single-photon source on the basis of confined Tamm plasmon modes. In [6,[14][15][16], the OTSs in magnetophotonic crystals were investigated. Gessler et al [17] studied the electrooptically tunable Tamm plasmon exciton polaritons.…”

Optical Tamm states at the interface between a photonic crystal and a gyroid layer

The spectral properties of a one-dimensional photonic crystal bounded by an absorbing plasmonic gyroid layer are investigated. The gyroid material is a foam-like metallic three-dimensionally periodic curved film with zero mean curvature at every point. We calculate the transmittance and reflectance spectra at the normal and oblique light incidence. The possibility of the Tamm state formation at the interface between a photonic crystal and a plasmonic gyroid layer caused by the negative real part of the gyroid permittivity is demonstrated for the first time. Specific features of field localization at the Tamm state frequencies are discussed. It is shown that the spectral and polarization properties of the optical Tamm states are highly sensitive to the change in the angle of incidence and in the refractive index of a medium filling the gyroid cavities.
