Spectrally Efficient Six-User Coherent OCDMA System Using Reconfigurable Integrated Ring Resonator Circuits

We demonstrate a spectral phase encoded optical code-division multiple-access system using programmable ring-resonator-based integrated coders. A six-user polarization multiplexed system operates at data rates of 5 Gb/s within an 80-GHz transparent optical window with a bit-error rate of 5times10-11 or better and a high spectral efficiency of 0.375 b/s/Hz
