和频法检测高功率双模压缩

Detection of high-power two-mode squeezing by sum-frequency generation

Faina Shikerman, Avi Pe'er

摘要:

我们引入和频产生(SFG)作为一种有效的物理双光子探测器的高功率双模压缩相干态的任意频率分离,所产生的参量振荡器远高于阈值。利用“集体模”的形式,我们描述了双模压缩和退化压缩的平等地位,并得出简单的输入压缩度和测量的SFG正交噪声之间的关系。我们比较建议的SFG检测标准零差测量,并显示在鲁棒性检测效率低下(SFG光子的损失)和接受带宽的优势。

英文摘要:

We introduce sum-frequency generation (SFG) as an effective physical two-photon detector for high power two-mode squeezed coherent states with arbitrary frequency separation, as produced by parametric oscillators well above the threshold. Using a formalism of "collective modes", we describe both two-mode squeezing and degenerate squeezing on equal footing and derive simple relations between the input degree of squeezing and the measured SFG quadrature noise. We compare the proposed SFG detection to standard homodyne measurement, and show advantages in robustness to detection inefficiency (loss of SFG photons) and acceptance bandwidth.
