    "abstract": "We report on the generation of polarization squeezing of intense, short light\npulses using an asymmetric fiber Sagnac interferometer. The Kerr nonlinearity\nof the fiber is exploited to produce independent amplitude squeezed pulses. The\npolarization squeezing properties of spatially overlapped amplitude squeezed\nand coherent states are discussed. The experimental results for a single\namplitude squeezed beam are compared to the case of two phase-matched,\nspatially overlapped amplitude squeezed pulses. For the latter, noise variances\nof -3.4dB below shot noise in the S0 and the S1 and of -2.8dB in the S2 Stokes\nparameters were observed, which is comparable to the input squeezing magnitude.\nPolarization squeezing, that is squeezing relative to a corresponding\npolarization minimum uncertainty state, was generated in S1.",
