- We report new experiments on polarization squeezing using ultrashort photonic pulses in a single pass of a birefringent fibre. We measure what is to our knowledge a record squeezing of -6.8±0.3 dB in optical fibers, which when corrected for linear losses is -10.4±0.8 dB. The measured polarization squeezing as a function of optical pulse energy, which spans a wide range from 3.5-178.8 pJ, shows a very good agreement with the quantum simulations, and for the first time we see the proof experimentally that Raman effects limit and reduce squeezing at high pulse energy.
