Combining the technologies of the waveguide multilayer storage and the memory card,we put forward a new technology of waveguide multilayer optical card(WMOC)read only memory(ROM)and its fabrication method.The WMOC ROM a low-index and transparent silicon rubber as the cladding layer material,and takes the advantage of soft lithography method to copy information to its surface at the same time.A 10 layer sample card and its detection results are also demonstrated in this paper.This card is fabricated using soft lithography method with cover glass as the core layer and PDMS as the cladding layer.
