MODULATING ELEMENT Russian patent published in 1995 - IPC

Abstract SU 1637555 A1

FIELD: optoelectronics. SUBSTANCE: invention can be used in magnetooptical Faraday-rotation modulators. Modulating element includes nonmagnetic garnet substrate 1 on which magnetic single-axis film 2 from ferrite-garnet with compensation of pulse moment is applied. Film 2 has composition Bi_xPr_y Er_3-x-yFe_5-zGa_zO₁₂, where 0,3≅x≅2,1;y≅0,5;1,1≅z≅1,7. EFFECT: achievement of easy-plane anisotropy and increase of Faraday effect. 5 cl, 1 dwg
