FIELD: physics.
SUBSTANCE: method of modulating optical radiation involves transmitting natural visible light in the wavelength range 350-850 nm at an angle of 5-75°, between the direction of the light and the perpendicular to the surface of the working optical element made from n layers of manganite A1-xBxMnO3 (where n≥1), wherein the trivalent rare-earth metal A is partially substituted with a univalent or divalent metal B with degree of substitution x. Visible light transmitted through and reflected from the working element is modulated under the effect of a control external magnetic field in which is located the working optical element, having giant visible light magnetotransmission and magnetoreflection effect.
EFFECT: wider range of methods of modulating optical radiation, simple design.
