Abstract

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