Abstract (in Japanese) (See Japanese page) 
(in English) Light waveguide based on a liquid with a modulated refractive index–magnetic fluid–is shown to control the flow of light by a spin subsystem. Polarization of light propagating in a magnetic fluid changes as the refractive index changes upon application of the external magnetic field. However, transmissivity of a magnetic fluid is low, and efficiency of the waveguide for optical applications is also low. In this work a new liquid magneto-optic device for modulating light intensity is studied. Optical extinction in a magnetic Fe3O4 fluid was compensated by a dye providing amplification. Study on the optical amplification rate by the dye was performed, showing that the polarization plane of amplified rays was kept.
