摘要: Owing to the presence of out-of-focus recording layers in volumetric optical disks. laser energy is decreased in reading/writing the targeted active layer. A non-linear optical material as an optical switch added to recording layers is proposed to modulate the optical characteristics of recording layers by diffraction limit laser spot impinged on it or not. The added optical switching structure can reduce laser energy and to increase recording sensitivity for reading and recording, respectively. Consequently. reading/recording on active layers of volumetric optical disks can be optimized.
