An optical arrangement includes a light source (20, 21) emitting polarized light, an analyzer (22), a component (10) containing a thin layer of ferromagnet amorphous metal whose optical properties can be varied by a magnetic field located between the light source and the analyzer, and a preferred direction of magnetization impressed on the magnetic layer. The magnetic layer mates an oblique angle with the direction of light propagation. The magnetic field which is impressed on the magnetic layer and whose direction can be changed by an external magnetic field changes the plane of polarization of light passing through the layer. A coil (13a, 13b) surrounding the magnetic layer and deposited by thin-film techniques turns the optical component into a light switch, and the optical arrangement containing the optical component into a transmitter of amplitude-modulated light. <IMAGE> |
