Abstract

A light-to-light conversion element which includes at least a photoconductive layer and a photo-modulation layer and in which light incident on these layers is reflected by a reflection layer and in which a selective reflection characteristic corresponding to color separation is given to the reflection layer. Thereby, among the light incident on the photoconductive layer and the photo-modulation layer, light having wavelength of the specific region is selectively reflected by the reflection layer, so that the write and read operation of information is performed on the selected light.
