A magnito photonic crystal of micro cavity-type contains layer of bismuth substituted iron - yttrium garnet of general formula Bi:YIG with a refractive index n, located between two Bragg mirrors. The layer of bismuth-substituted iron-yttrium garnet is made of BiYFeO, where z = 0,5-3,0 at. / form. units, Bragg mirrors are made of 3 ≤ N ≤ 10 pairs of layers with refractive indices nand n. At that the difference of refractive indices is n-n≥ 0,5, and n> n, the Bragg mirrors and a layer of bismuth substituted iron - yttrium garnet are made removable along one side and constant along the other, perpendicular to the first side of the crystal by thick end. The thickness in Bragg mirrors is quarter-wave, and the thickness of the layer BiYFeOis half-wave for light incident on the points that lie on the lines of constant thickness of the microresonator. |
