摘要： PROBLEM TO BE SOLVED: To record optical information at high density by utilizing that when a thin film having azobenzene is irradiated with linearly polarized light, molecules are oriented in a direction perpendicular to an oscillation direction of an electric field and high birefringence is generated. SOLUTION: The degree of chirality (the magnitude of optical rotation) induced in a photo-responsive thin film material (especially the azobenzene thin film) by the irradiation of elliptically polarized light depends on an irradiation amount with light, a wavelength of light and an ellipticity and an azimuthal angle of the elliptically polarized light. Accordingly, optical rotation performance can be imparted to the thin film by irradiating the photo-responsive organic thin film with the elliptically polarized light. COPYRIGHT: (C)2008,JPO&INPIT
