摘要

研究了利用自发参量下转换产生非经典光太赫兹双光子的必要条件。利用热电子测热仪，我们演示了以创纪录的低增益检测参数上下转换产生的太赫兹频率闲散波。在低温下观察到经典的贡献完全消失。分析了二阶双光子相关函数。

Preparation of the Quantum Correlated Optical-Terahertz Biphotons

We study the conditions necessary for generating non-classical optical-terahertz biphotons by means of spontaneous parametric down-conversion. Using a hot electron bolometer we demonstrate detection of the THz-frequency idler waves generated under parametric up- and down-conversion with a record low gain. Complete disappearance of the classical contribution has been observed at low temperatures. A second-order biphoton correlation function is analyzed.
