Paper Abstract

In our laboratory, new three-dimensional memory using interference pattern caused by void array has been proposed. In this method, Interference pattern is obtained by irradiating visible laser to void arrays as a slit. Information has been written in transparent materials with void array and read out with interference pattern analysis and the void array restoration. The void creating from 4&mgr;m to 10&mgr;m has been successful using nano-pulse Nd: YAG laser. These created voids are fulfilled conditions of forming an interference pattern. It is suggested that reading out of information has been available using interference pattern. Probability of the void creating is too low and a crack might be generated on the past investigation. In this study, the parameter of irradiation energy and number of irradiation has been explored for the void creating with high probability.
