We report a detailed experimental study of vector modulation instability in highly birefringent optical fibers in the anomalous-dispersion regime. We prove that the observed instability is mainly induced by vacuum fluctuations. The detuning of the spectral peaks agrees with linear perturbation analysis. The exact shape of the spectrum is well reproduced by numerical integration of stochastic nonlinear Schrödinger equations describing quantum propagation.
我们报告了在反常色散区域中高度双折射光纤内矢量调制不稳定性的详细实验研究。我们证明，观察到的不稳定性主要由真空涨落引起。光谱峰的失谐与线性微扰分析一致。通过描述量子传播的随机非线性薛定谔方程的数值积分，很好地再现了光谱的精确形状。
