摘要
In the last years, acousto-optic (AO) interaction has been proved to be a powerful and highly sensitive method for fine characterization of optical fibers. The key of the technique relies on the high sensitivity of the AO phasematching condition with the structural and material properties of the fiber, enabling the detection of subnanometer fiber radius variations, or core refractive index variations in the order of 10(-8) in single-mode fibers. In this contribution, we present our results on the use of in-fiber AO interaction for the measurement of the nonlinear refractive index in single-mode optical fibers.
