利用抽运光和探测光之间的交叉相位调制（XPM）效应测量了标准单模光纤中的电致伸缩非线性。相干零差接收器的新颖使用允许测量探测场的同相和正交分量，消除了对光学干涉仪的需要。实验表征了克尔效应（γ<sub>k</sub>）和频率相关的电致伸缩（γ<sub>e</sub>）非线性参量，发现在最高峰值共振频率处，γ<sub>e</sub>约为γ<sub>k</sub>的1/3。当泵和探针不共极化时，γ<sub>k</sub>和γ<sub>e</sub>的联合作用也引入了电致伸缩信号的极化依赖性。
The electrostriction nonlinearity in a standard single mode fiber is measured by cross-phase modulation (XPM) between pump and probe. Novel use of a coherent homodyne receiver allows measurement of in-phase and quadrature components of the probe field, eliminating the need for an optical interferometer. The Kerr effect (γ<sub>k</sub>) and frequency-dependent electrostriction (γ<sub>e</sub>) nonlinear parameters are characterized experimentally, and γ<sub>e</sub> is found to be approximately one third of γ<sub>k</sub> at the highest peak resonance frequency. The joint action of γ<sub>k</sub> and γ<sub>e</sub> also introduces a polarization dependence of the electrostrictive signal when the pump and the probe are not copolarized.
