Abstract: A new en/decode scheme of OCDMA—waveguide en/decoder is proposed. The principle of waveguide en/decoder is analyzed. The structure of waveguide en/decoder is given. It can also be seen that all-optical CDMA en/decoder can be realized by the proposed scheme of waveguide en/decoder.It can easily made the OCDMA en/decoder integrated.It can also made the access be controlled easily.

Key words: optical fiber communication, optical code division multiple access, waveguide, en/decoder
