We report on the detection of picosecond pulsed squeezed light generated by an optical parametric amplification in a periodically poled MgO : LiNbO 3 waveguide. By using a temporally shaped local oscillator in a balanced homodyne detection, we obverved the squeezing of 5.0 dB below the shot noise level. The squeezing level at the exit of the waveguide was estimated to be 9.7 ± 0.8 dB .
