Abstract :
The authors construct a new family of 2n codes, called 2n extended prime codes, for all-optical code-division multiple access (AOCDMA) applications. Such 2n codes are obtained by “extending” prime codes. As a result, the cross-correlation constraint of the new codes is equal to one, as opposed to two in the original prime codes or 2n prime codes. Moreover the bit error rate (BER) of AOCDMA systems using the new codes is analysed. It is shown that the new codes can support a larger number of active users than the 2n prime codes for a given BER
