Abstract

We investigate the use of differential detection in two-dimensional (2D) wavelength-time Optical Code-Division Multiple Access (OCDMA). We develop and analyze the bit-error-rate (BER) performance for a new family of high-weight 2D codes with relaxed auto- and cross-correlation, which we call balanced codes for differential detection (BCDD), that take advantage of the antipodal signaling strategy enabled by differential detection. We find that BCDD's can effectively be used to implement high-performance 2D wavelength time OCDMA networks. Using an OC-3 transmission rate of 155Mbps, a BCDD system with 32 wavelengths, 41 time-chips and suitable error-control coding can support up to 320 users with bit error rate of 10-9, giving rise to an aggregate capacity of 41Gbps.
