Abstract

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 ( $\gamma _{k}$ ) and frequency-dependent electrostriction $(\gamma _{e})$ nonlinear parameters are characterized experimentally, and $\gamma _{e}$ is found to be approximately one third of $\gamma _{k}$ at the highest peak resonance frequency. The joint action of $\gamma _{k}$ and $\gamma _{e}$ also introduces a polarization dependence of the electrostrictive signal when the pump and the probe are not copolarized.
