A novel OCDMA en/decode scheme in wavelength/time domain is proposed. The scheme use the extend hyperbolic and linecode (EHLC)/prime code (PC) with arrayed waveguide grating (AWGs). The two-dimension EHLC/PC-code in the en/decoding scheme is investigated by computer simulation. It is indicated that the AWGs can be employed as en/decoder on basis of EHLC/PC-code. The more number of userscan be accessed in the same code length and code weight in this system. Moreover, AWGs en/decoder is easy to be integrated.
