Magnetoplasmonic waveguiding structure with nonreciprocal dispersion of guided TM modes

In this paper we present our study of waveguiding structure with nonreciprocal dispersion of guided modes. The considered structure is based on the Silicon waveguide core and the plasmonic (gold) 1D periodic grating. The waveguide and the grating are separated by low refractive index layer (SiO2). The structure operates as follows. The evanescent field of the guided mode is used for the excitation of the surface plasmon polaritons (SPPs) at the top side of the grating. To achieve non-reciprocity the magneto-optical dielectric garnet is assumed to be on the top of the grating. The presence of the transversal magnetization in the garnet leads to the nonreciprocal shift of the SPP. Together with the evanescent coupling of guided modes this leads to the nonreciprocal dispersion of guided mode. The grating period is varied to achieve coupling of grating’s resonances with the waveguide evanescent field and therefore possible enhancement of the nonreciprocal response.
