Abstract

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.
