Abstract: The arrangement of molecules of an optical activity compound such as polymer including azo-dye is changed by the polarization state of a pump beam applied to the polymer. The polymer is polyvinyl alcohol including methyl orange as azo-dye. The anisotropy of the molecular arrangement of the azo-dye is induced by the polarized incident beam and then the liquid crystal cell is made. Thereafter, the liquid crystal is inserted to the cell, aligning the liquid crystal. As the polarization of the pump beam changes from the linear polarization to the circular polarization, molecules of the methyl orange are exponentially increased at an axis parallel to the propagation direction of the pump beam and the molecules of the methyl orange are exponentially decreased at an axis vertical to the propagation direction of the pump beam.
