A 40Gbits hybrid optical code-division multiplexing (OCDM)/ wavelength-division multiplexing (WDM) system is experimentally demonstrated and simultaneous multiwavelength optical encoding of a single supercontinuum source using superstructured fiber Bragg grating is achieved. The interchannel interference and noise of the OCDM/WDM system is suppressed apparently by incorporating a nonlinear amplifying loop mirror, both the sidelobe and the pedestal are reduced, the waveform quality of decoded signal is improved, and the original 8.2ps autocorrelation peak of decoded pulse is compressed to 4.8ps.
