The Study of OCDMA Encode/Decode Using Multilayer Films

A new encode/decode scheme of OCDMA—films encode/decoder is proposed. The principle of films encode/decoder is analyzed. The system structure of films encode/decoder is given. It can also be seen that all optical CDMA encode/decode can be realized by the proposed system of films encode/decoder.At the same time, the OCDMA encode/decoder can be integrated easily.It can also made the access be controlled easily.
