Paper Abstract

We demonstrate the security improvement using ±π/2-phase-shifted SSFBG encoder in time-spreading OCDMA. Compared with conventional 0/π-phase-shifted SSFBG encoder, ±π/2-phase-shifted SSFBG encoder conceals code pattern well in the encoded waveform. We also theoretically analyze and experimentally investigate the influence of input pulse and the experimental measurement matches the calculated result very well.
