The method of spatial separation of optical modes of orthogonal polarizations in a planar waveguide structure

摘要

FIELD: optics.SUBSTANCE: invention relates to integral optics. Method of spatial separation of the optical modes of orthogonal polarizations in a planar waveguide structure, which consists in the fact that the laser radiation is introduced into a four-layer planar guide structure, consisting of a base, a coating medium, a waveguide high refractive magneto-optical layer, magnetized to saturation in the plane of the interface, in the direction transverse to the propagation of light, a waveguide nanocomposite layer with a lattice coupling element located on its surface for introducing radiation. Adjustment for a given wavelength, given input angles and separation of waveguide modes of orthogonal polarizations is carried out by selecting the ratio of the thicknesses of dielectric nanolayer of two types in the nanocomposite layer.EFFECT: technical result consists in increasing the efficiency of the polarization separation of light in planar guide structures of integrated optics.4 cl, 3 dwg
