脉冲纠缠双光子场的性质

Properties of pulsed entangled two-photon fields

Jan Perina

摘要:

研究了自发参量下转换中产生的脉冲纠缠双光子场的单光子和双光子特性对泵浦脉冲特性(泵浦脉冲谱的形状及其内部结构)的依赖关系。结果表明,可以产生具有特定性质的纠缠双光子场。下转换场的频谱之间的一般关系的建立。作为一种特殊情况,研究了两个部分重叠的脉冲双光子场的干涉。在Hong-Ou-Mandel干涉仪的偏振模拟中,研究了纠缠双光子场的四阶干涉图样。

英文摘要:

The dependence of one- and two-photon characteristics of pulsed entangled two-photon fields generated in spontaneous parametric down-conversion on the pump-pulse properties (shape of the pump-pulse spectrum and its internal structure) is examined. It is shown that entangled two-photon fields with defined properties can be generated. A general relation between the spectra of the down-converted fields is established. As a special case interference of two partially overlapping pulsed two-photon fields is studied. Fourth-order interference pattern of entangled two-photon fields is investigated in the polarization analog of the Hong-Ou-Mandel interferometer.
