Abstract
We utilize a nonuniform encoding scheme for spectral phase encoding in optical code-division-multiple-access networks. This method improves the orthogonality of encoded waveforms between multiple users under synchronous transmission by compensating for the nonideal spectral shape of the subpicosecond mode-locked laser pulse source. Simulation results demonstrate five orders of magnitude of bit-error-rate reduction compared with the traditional uniform encoding scheme
