Nonlinear Crosstalk Due to XPM in Single-sideband ROF Systems
单边带调制ROF链路中交叉相位引起的非线性串扰

The nonlinear crosstalk due to cross-phase modulation was studied by a new analysis model in single-sideband radio over fiber (ROF) systems, and the results were compared with that of the pump-probe method,which could be used to analyze different links, in particular, electrooptical upconversion links. Detailed analyses of the crosstalk due to cross-phase modulation for links with optical single-sideband modulation were presented. The nonlinear crosstalk due to cross-phase modulation have relation to the modulation frequency, the power of the pump and probe and the channel space. The simulation results agree well with the theoretical analysis.
