40-Gbit/s OCDM/WDM system based on supercontinuum source and SSFBG

摘要

40-Gbit/s optical code-division multiplexing (OCDM)/ wavelength-division multiplexing (WDM) system based on supercontinuum (SC) and superstructured fiber Bragg grating (SSFBG) is experimentally demonstrated, simultaneous multi-wavelength optical encoding of a single supercontinuum source using SSFBG is achieved. In the receiver, a nonlinear amplifying loop mirror (NALM) is introduced to improve the system performance, both the sidelobe and the pedestal are reduced, the waveform quality of decoded signal is enhanced. The peak power of the decoded signal before the NALM is ～ 8 mW.
