我们报告了在周期性极化的 MgO:LiNbO(3) 波导中通过光学参量放大产生的皮秒脉冲压缩光的检测。通过在平衡零差检测中使用时间形状的本地振荡器，我们观察到散粒噪声水平压缩了 -5.0 dB。波导出口处的挤压水平估计为-9.7±0.8 dB。
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.
