We report the design of a new family of two-dimensional codes for fiber-optic CDMA networks. These newly designed temporal/spatial single-pulse-per-row (T/S SPR) codes have out-of-phase autocorrelation zero and cross correlation equal to one. Optical orthogonal codes (OOC's) have the lowest out-of-phase autocorrelation and cross-correlation values (both equal to one) among the one-dimensional codes. We compare the performance of our codes to the OOC's for a given probability of error. Experimentally we verify the autocorrelation and cross-correlation properties of our codes and Park et al.  codes.
