A three‐chip, 240‐Gchip/s quaternary phase‐shift code is assigned to short pulses after reflection from a encoder. The code is then recognized by a decoder. The encoder and decoder consist of superstructured fiber Bragg gratings (SSFBGs). The quaternary phase encoding and decoding of short pulses at 40 Gb/s is experimentally demonstrated, and it is required in optical‐code division multiplexing (OCDM) systems and packet‐switched networks. © 2006 Wiley Periodicals, Inc.
