    "abstract": "To the best of our knowledge, we demonstrate for the first time the\ngeneration of photon number squeezing by spectral filtering for ultra-broadband\nlight generated by microstructure fibers at 800 nm. A maximum squeezing of 4.6\ndB is observed, corresponding to 10.3 dB after correcting for detection losses.\nWe numerically analyzed the quantum dynamics of ultrashort laser pulse\npropagation through optical fibers by solving a nonlinear quantum Schrodinger\nequation that included Raman scattering, especially for the quantum correlation\nof photon number fluctuation among frequency modes in broadband pulses.",
