[Abstract]:The analytical solution of degenerate four-wave mixing (DFWM) of HNLFs in high nonlinear optical fiber under pump consumption is described in detail. The expressions of output power and phase of guided light are given in combination with the first class, the third type elliptic integral and the Jacobian elliptic function. For the convenience of calculation and analysis, the calculation commands of special functions in Matlab are given. The necessary conditions for multilevel regeneration based on DFWM are analyzed by using the analytical formula. The effects of the initial phase and initial power of pump light on the phase transfer curve of MPSK signal during phase sensitive amplification are studied. It is shown that adjusting the initial phase of the pump light can match the phase transfer curve of the phase sensitive amplifier PSAs with the multi-level phase of the input signal. Optimizing the length of the fiber or the initial power of the pump light can obtain the maximum performance of the multi-level phase regeneration jitter suppression. The optimized initial pump power is approximately inversely proportional to the fiber length. The performance of the 8PSK signal regenerator based on PSA is simulated by OptiSystem software, and the simulation results are consistent with the theoretical analysis, when the normalized input phase jitter is 0.1, The jitter suppression ratio of the phase regenerator is 4.62, which can reduce the symbol error rate of the system by two orders of magnitude.
