Direct measurement of the nonlinear phase shift between the orthogonally polarized states of a single-mode fiber.
We measure the phase shift induced by the optical Kerr effect between the two orthogonally polarized states of a birefringent single-mode fiber. The associated noise, which can arise whenever amplitude fluctuations of the source are present, is discussed.
