Abstract

Photon-number squeezing of optical pulses using optical fibers and band-pass spectral filters is numerically analyzed. The evolution of the quantum noise in the optical pulse propagation is calculated in both the spectral and time domains. The mechanism of filtering squeezing and the role of the group-velocity dispersion are investigated. It is shown that the squeezing is realized owing to the interaction between the self-phase modulation and the group-velocity dispersion.
