Abstract
A misaligned optical carrier (MOC) polarization division multiplexing single-sideband optical orthogonal frequency division multiplexing (PDM-SSB-OOFDM) scheme with a single balanced detection-based beat interference cancellation receiver (BICR) is proposed for transmitting two SSB-OOFDM signals. In this PDM-SSB-OOFDM system, the signal-signal beat interference (SSBI) is eliminated and the receiver is simplified. Since the receiver is implemented by only one BICR without polarization beam splitting and complicated MIMO processing, the system is not sensitive to polarization mode dispersion (PMD) and is easy to implement. The proposed MOC PDM-SSB-OOFDM scheme is demonstrated by the simulation, and two 40 Gb/s 16-ary quadrature amplitude modulation (16-QAM) signals are transmitted over a 120 km standard single mode fiber (SSMF) with an error vector magnitude (EVM) below 16.3%.
