Abstract

A polarization-shift-keying (POLSK) homodyne system using phase-diversity receivers is proposed. It has the advantages of both the homodyning and the polarization modulation scheme. Hence, it is attractive at a high bit rate and has no power penalty and no floor due to the influence of phase noise and offset frequency in the bit-error-rate (BER) performance. The authors theoretically analyze the receiver sensitivity and find that it is equal to that of the POLSK heterodyne system and that at a high signal-to-noise ratio (SNR), the degradation of the receiver sensitivity in the proposed system is much smaller than that in DPSK phase-diversity homodyne systems
