Abstract
A spectral-polarization coding (SPC) optical code-division multiple-access (OCDMA) configuration structured over arrayed-waveguide grating (AWG) router is proposed. Polarization-division double balanced photo-detector is adopted to enhance system performance. The experimental results demonstrate the system embedded with orthogonal state-of-polarization (SOP) will suppress effectively phase-induced intensity-noise (PIIN). By mathematical analysis, the coding schemes and interference eliminations are described in detail. The signal-to-noise ratio (SNR) is derived by taking the effect of PIIN into account. The result indicates that there would be up to 9-dB SNR improvement than the conventional spectral-amplitude coding (SAC) structures with Walsh-Hadamard codes.
