Abstract
A new family of 2n
codes, called 2n extended-prime
codes, is proposed for all-optical code-division multiple-access networks.
Such 2n codes are derived from
so-called extended-prime codes so that their cross-correlation functions are
not greater than 1, as opposed to 2 for recently proposed
2n prime codes. As a result, a
larger number of active users can now be supported by the new codes for a given
bit-error rate than can be by 2n
prime codes, while power-efficient, waveguide-integrable all-serial coding and correlating configurations proposed for the 2n prime codes can still be employed.
