We have directly measured the amount of birefringence induced by nonlinear Kerr effect in standard optical fibers, by means of a double-polarization-heterodyne method, suitable for characterizing short samples of fibers. Birefringence is measured with a resolution of /spl Delta/n/spl ap/10/sup -12/ and the optical Kerr coefficient is extracted. The agreement of experimental results and theoretical predictions confirms the accuracy of the technique.

Abstract
We have directly measured the amount of birefringence induced by nonlinear Kerr effect in standard optical fibers, by means of a double-polarization-heterodyne method, suitable for characterizing short samples of fibers. Birefringence is measured with a resolution of /spl Delta/n/spl ap/10/sup -12/ and the optical Kerr coefficient is extracted. The agreement of experimental results and theoretical predictions confirms the accuracy of the technique.File in questo prodotto:
