Spectrally coded O-CDMA system with four users at 2.5 Gbit/s using low power nonlinear processing

摘要

A four-user 2.5 Gbit/s optical code-division multiple-access (O-CDMA) system is demonstrated at ≤10~(-11) BER utilising programmable spectral phase encoding, an ultrasensitive (<0.4 pJ/bit) PPLN-wave-guide nonlinear waveform discriminator, and a 10G Ethernet receiver.
