title: Observation of squeezed light at 1.535 microm using a pulsed homodyne detector.
abstract: Squeezed light was generated at a telecommunication wavelength via single-pass optical parametric amplification in a periodically poled MgO-doped LiNbO(3) waveguide. Classical parametric deamplification of -8.9 dB was achieved. This large magnitude of deamplification indicates that the problem of gain-induced diffraction was avoided by employing the waveguide. Squeezing of 3.2 dB was directly observed using a time-domain pulsed homodyne detector.
