Evolution of Beat Signal in a Nonlinear PCF Considering the Stability of the Light Source
The spectrum evolution of the beat signal can be used to measure the nonlinear coefficient of the fiber. By theoretical simulations, for the first time, we analyzed the effect of the stability of the output power, the frequency and the linewidth of the laser on the measurement of the nonlinear coefficient. The simulations show good agreement with the experiments in which all impacts are involved. The transmission process and the evolution spectra of the beat signal propagating along the PCF are analyzed by using the Split-Step Fourier Method with the consideration of self-phase modulation, fiber loss and dispersion. The results show that the stability of the laser output power has little effect on the measurement of the nonlinear coefficient, but the linewidth and the stability of the central wavelength have more effects on it.
