Abstract :
Two-dimensional (2-D) parallel optical data link based upon optical space-CDMA is implemented and experimentally demonstrated for the first time to the authors´ knowledge. In the experiment, the encoded bit-planes are spatially multiplexed, and it is transmitted through a 16 m-long image fiber having 3×104 pixels. Each input 4×4 bit-plane is optically encoded by an 8×8 2-D optical orthogonal signature pattern. Each receiver can properly recover the intended input bit-plane via the optical decoding process. This result will encourage the application of optical space-CDMA to future high-throughput 2-D parallel data links connecting massively parallel processors
