title: Elasto-optic polarization measurement in optical fiber.
abstract: A method is described for the nondestructive determination of the state of polarization of the guided light at an arbitrary point along a single-mode fiber. The fiber is squeezed laterally with a small, periodic (75-Hz) force. The azimuth of the force is varied. The resulting elasto-optic polarization modulation is detected at the fiber end and is evaluated for the azimuth and ellipticity of the polarization at the point of modulation.
