摘要
A 7-chip, 280 Gb/s optical code-division multiplexing （OCDM） system incorporating quaternary phase coding and decoding superstructured fiber Bragg gratings （SSFBGs） is experimentally demonstrated. Only ordinary phase masks and sub-micrometer precision are needed to fabricate the encoding and decoding SSFBGs. Interchannel interference noise is also considered and evaluated, 2-channel 40 （Gb/s）/channel （2 ×40 Gb/s） signal transmission is demonstrated.
