OPTICAL MEMORY DEVICE USING PLASMON TRANSFER

摘要

An optical memory device using plasmon transfer is provided to phase-change nano dots by scanning light to the nano dots so as to transfer light instead of transferring electrons, thereby obtaining an optical memory using the light and storing data in the memory easily. An optical memory device comprises a light input part(110), a light output part(120), a plurality of nano dots(N1~N5), and a light exciting part(140). Light is inputted to the light input part which is placed on a substrate(100). The light output part outputs light. The nano dots, made of GeSbRTe, are placed between the light input part and the light output part. The light exciting part is formed on one side of the nano dot to phase-change the nano dot by scanning light to the nano dot.
