Abstract

One new wavelength-time coding scheme is proposed for high-speed optical code division multiple access(OCDMA) networks, and a large number of new codes with asymptotically optimal cardinalities can be generated by this coding scheme. This makes the codeword patterns more random and thus the resulting OCDMA networks are more robust against the eavesdroppers.
