Abstract
We develop a novel bipolar two-dimensional coding scheme for optical code-division multiple-access (OCDMA) communication systems. The coding scheme is based on complementary spectral amplitude coding of broad-band sources in the wavelength domain and as such enables multi-user operation and bipolar signaling. To significantly increase the number of simultaneous users a spreading sequence in the time domain is imposed on the wavelength domain coding. We analyze the performance of a LAN system based on the proposed coding scheme, and show that the coders can be realized via simple and compact hardware.
