Efficient generation of tunable photon pairs at 0.8 and 1.6 micrometer

Elliott J. Mason, Marius A. Albota, Friedrich Koenig, Franco N. C. Wong

摘要:

我们证明了在一个双极化的锂离子酸盐连续波参量下变频器中有效地产生共线传播的高度非简并光子对,其对产生速率为1.4*10^7/s/mW的泵浦功率。800 nm信号光子的检测触发热电冷却的20%效率的InGaAs雪崩光电二极管,用于检测1600 nm共轭闲频光子。使用单模光纤作为空间模式滤波器,我们得到了约3.1%的信号调节空闲检测概率。

英文摘要:

We demonstrate efficient generation of collinearly propagating, highly nondegenerate photon pairs in a periodically-poled lithium niobate cw parametric downconverter with an inferred pair generation rate of 1.4*10^7/s/mW of pump power. Detection of an 800-nm signal photon triggers a thermoelectrically-cooled 20%-efficient InGaAs avalanche photodiode for the detection of the 1600-nm conjugate idler photon. Using single-mode fibers as spatial mode filters, we obtain a signal-conditioned idler-detection probability of about 3.1%.
