光环中光的偏振态起伏是严重影响基于循环移频器的多载波光源输出性能的重要因素。从理论上分析了无偏振控制器时输出频谱不稳定的原因。数值模拟了多载波源在有无光子晶体情况下的输出频谱，比较了各频率分量偏振态在有无光子晶体情况下在庞加莱球上的运动轨迹。结果表明，通过适当调整PC的配置，可以有效地提高基于RFS的多载波信号源的性能。
Fluctuating polarization state-of-light in the optical loop is an important factor that seriously influences the output performance of a multi-carrier source based on re-circulating frequency shifter (RFS). The reason for output spectrum instability when no polarization controller (PC) is present in the loop is analyzed theoretically. Numerical simulations for the output spectra of the multi-carrier source with and without PC are conducted, and the trajectories of the several frequency components polarization states on the Poincare sphere with and without PC are compared. The results show that the performance of multi-carrier source based on a RFS can be improved effectively by adjusting the PC in the configuration properly.
