Photon number squeezing of spectrally filtered optical solitons has been
observed in the sub-picosecond regime, where the Raman effect changes
the internal quantum structure of each pulse. 160 fs pulses were
propagated down a 10 m optical fibre of anomalous group velocity
dispersion. At energies below the soliton energy subsequent spectral
filtering with an optical band-pass squeezed the directly detected
photocurrent fluctuations to 3.2 +/- 0.1 dB (52%) below the shot-noise
limit. This implies 4.5 dB (65%) of soliton photon number squeezing, if
detection losses are taken into account. Using a spectral edge filter
the spectral components of the pulses are shown to contribute
asymmetrically to the squeezing due to stimulated Raman scattering.
