All-optical wavelength conversion (AOWC) for 160Gbps polarization division multiplexing OFDM (PDM-OFDM) 16QAM signal in semiconductor optical amplifier (SOA) is theoretically simulated and realized in this paper. An external cavity laser is employed as the dual-pump seed. The measured result shows that the polarization insensitive converted signals can be achieved based on coherent detection without...
Twice real-valued FastICA (TR-FastICA) algorithm is proposed in this paper to eliminate crosstalk between the two polarization multiplexed complex-valued higher-order quadrature modulation format such as QPSK signals induced by polarization mode coupling with polarization mode dispersion (PMD) and polarization dependent loss (PDL) for the coherent optical polarization division multiplexing (CO-PDM)...
The system based on orthogonal pump four-wave mixing in an SOA is theoretically analyzed and simulated. The simulation results show that the polarization insensitive converted signal can be separated into two lightwaves without crosstalk.
We analyzed the performance of DFE in PMD-limited 40 GB/s Optical links by using Matlab/Simulink. We also provided a description of the equalizer circuit design, and described the results of circuit simulations; it is found that a DFE consisting of a 3-tap FFE and a 2-tap FBE could compensate PMD.
