We report on a novel and efficient source of polarization squeezing that uses a single pass through an optical fiber. Using the fiber's two orthogonal polarization axes produces two identical squeezed beams. Combining these in a Stokes measurement generates polarization squeezing of up to 5.1±0.3 dB. Furthermore, this scheme enables us to directly measure, for both polarizations, the noise of any given quadrature.
