摘要：<P>PROBLEM TO BE SOLVED: To provide a refractive index modulation structure and an LED device that can improve a light modulation rate. <P>SOLUTION: A refractive index modulation structure comprises a moth-eye structure that includes a material on which surface recesses or protrusions are formed periodically; and an electric-field regulating section that generates an electric field in the material thereby varies the refractive index of the material. The transmission condition of diffraction is varied by the variation in the refractive index of the moth-eye structure. <P>COPYRIGHT: (C)2012,JPO&INPIT
