optical fiber中光子对的发射--零点涨落的影响

Emission of photon pairs in optical fiber -- effect of zero-point fluctuations

V. Hizhnyakov

摘要:

考虑了一个非线性量子光学过程:由激光驻波激发的光纤反射端的光子对发射。由于光纤的光学长度随时间的周期性变化而发生辐射。这种辐射在长纤维中可以显著增强。由于这种增强,一个非微扰描述的过程是必需的。如果光程振荡的振幅与激光波长的一半一致,这里提出的这种描述预测了强辐射峰。所考虑的现象可以用于创建纠缠光子的源。

英文摘要:

A nonlinear quantum-optical process is considered: emission of photon pairs by the reflecting end of a fiber excited by a standing laser wave. Radiation occurs due to periodic changes in the optical length of the fiber over time. This radiation can be significantly enhanced in long fibers. Because of this enhancement, a nonperturbative description of the process is required. Such a description presented here predicts a strong peak of radiation, if the amplitude of the oscillations of the optical length coincides with half of the laser wavelength. The considered phenomenon can be used to create a source of entangled photons.
