Abstract :
A multi-user code-shift-keying (CSK) optical CDMA system is demonstrated with 511-chip SSFBG en/decoder and balanced detection. The comparison experimental investigation shows that, besides the enhancement of confidentiality, the multi-user capability can be significantly improved over on-off-keying and CSK-OCDMA with single detector due to the better noise tolerance.
