We propose and analyze a novel all-optical fiber polarization scrambler based on the transfer (via the Kerr effect) of the intensity fluctuations of an incoherent pump beam into polarization fluctuations of a frequency-shifted signal beam, copropagating in a randomly birefringent telecom fiber. Optimal signal polarization scrambling results whenever the input signal and pump beams have nearly orthogonal states of polarization. The nonlinear polarization scrambler may operate on either cw or high-bit-rate pulsed signals.
我们提出并分析了一种新型的全光纤偏振扰频器，它基于非相干泵浦光束的强度涨落（通过克尔效应）转换为频移信号光束的偏振涨落，该信号光束与泵浦光束在随机双折射的通信光纤中同向传播。当输入信号光束和泵浦光束具有近乎正交的偏振态时，可实现最佳的信号偏振扰频效果。这种非线性偏振扰频器可用于连续波或高比特率脉冲信号。
