Abstract

Code scrambling combined with self obscuration in a spectral phase encoded OCDM system shows promise for enhanced confidentiality in high data rate networks. We demonstrate code scrambling using reconfigurable ring-resonator-based integrated coders for obscuring a 20 Gb/s OCDM signal comprising four polarization multiplexed coded tributaries.
