非线性环形光纤中OAM纠缠光子对的自发参量下转换发射

Emission of OAM entangled photon pairs in a nonlinear ring fiber utilizing spontaneous parametric down-conversion

D. Javůrek, J. Svozilík, J. Peřina

摘要:

我们提出在热致非线性极化石英光纤中通过自发参量下转换产生光子对。光子直接在光学角动量的本征态中产生。一对光子可以在这些状态以及频率上纠缠。我们确定合适的空间和偏振模式,提供一个有效的非线性相互作用。通过改变抽运光场的性质,可以得到窄带和宽带下转换光场。

英文摘要:

We suggest the generation of photon pairs in a thermally induced nonlinear periodically-poled silica fiber by spontaneous parametric down-conversion. Photons are generated directly in eigenstates of optical angular momentum. Photons in a pair can be entangled in these states as well as in frequencies. We identify suitable spatial and polarization modes giving an efficient nonlinear interaction. By changing the pump field properties both narrow- and broad-band down-converted fields can be obtained.
