All-serial coding architecture for ultrafast optical code-division multiple-access

Abstract

An all-serial coding architecture for ultrafast optical CDMA (code-division multiple-access), particularly suitable for waveguide and free-space operations, is studied. Performance comparison of the prime, 2/sup n/, and modified 2/sup n/ encoders/decoders in terms of normalized delay and ideal power loss reveals that the modified 2/sup n/ encoders/decoders perform the best. A 100 Mb/s optical CDMA experiment in free space using 100-fs laser pulses has been performed.<>
