Abstract

We report new experiments on polarization squeezing using ultrashort photonic pulses in a single pass of a birefringent fiber. We measure what is to our knowledge a record squeezing of 6.8±0.3dB in optical fibers, which when corrected for linear losses is 10.4±0.8dB. The measured polarization squeezing as a function of optical pulse energy, which spans a wide range from 3.5178.8pJ, 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.

Diamonds show the experimental results of the (a) squeezing angle, (b) squeezing, and (c) antisqueezing for the 13.2 m fiber. Error bars on the squeezing data indicate the uncertainty in the noise measurement; for the antisqueezing, the error bars were too small to be plotted. Solid and dashed curves show the simulation results with and without additional phase noise, respectively. Dotted curves indicate the sampling error in the simulation results.
