我们提出了在通信波长为1.535 μ m的脉冲压缩光的产生，通过单通参量放大周期性极化MgO掺杂的LiNbO 3波导使用一种新的共线配置。在时域内测量了压缩光场的正交振幅。观察到经典参量衰减为-3.2dB和正交压缩为-1.5dB。利用光波导的严格限制和脉冲光的高峰功率，在平均泵浦功率为0.47 mW时获得了19.3 dB的最大经典参量放大。
We present the generation of pulsed squeezed light at telecommunication wavelength of 1.535 mu m via single-pass parametric amplification in a periodically poled MgO-doped lithium niobate waveguide using a novel collinear configuration. The quadrature-amplitude of squeezed light is measured in time domain. The classical parametric deamplification of -3.2 dB and quadrature squeezing of -1.5 dB are observed. The maximum classical parametric amplification of 19.3 dB is obtained at pump average power of 0.47 mW, taking advantage of the tight confinement in a waveguide and high peak power of the pulsed light.
