OCDMA offers great promise for high-capacity, secure, and flexible fiber optic communication, but performance remains suboptimal because of speckle noise, optical time gating, and nonlinear detection. A recently proposed [1] new method for interference-cancelling, phase coherent demodulation of spectrally encoded OCDMA potentially achieves high spectral(More)
A novel coherent optical code division multiple access (OCDMA) network based on phase and polarization diversity balanced reception of spectrally encoded optical pulses is proposed. Spectral efficiencies of 1 bps/Hz and beyond can be achieved by minimizing multiple access interference (MAI) and by cancelling beat noise. While the system achieves full(More)
