动态卡西米尔效应是由于系统参数或边界条件的非绝热变化而从真空中产生成对的真实的粒子或光子。与在空间和时间上都发生调制的标准参量放大相反,这种基本过程需要时间上的纯调制,这使得其在光频率下的检测特别具有挑战性。在本文中,我们实验证明了在近红外光学制度的色散振荡光子晶体光纤中的模拟动力学Casimir效应的实现。实验是基于等效的空间调制的光纤芯直径的纯时间调制时,这是考虑在共同移动的帧中的行进泵浦脉冲。我们通过测量光谱分辨光子对之间的量子关联提供了光学动力学Casimir效应的证据,并证明了它们的非经典性质与光子反聚束。
The dynamical Casimir effect is the generation of pairs of real particles or photons from the vacuum as a result of a non-adiabatic change of a system parameter or boundary condition. As opposed to standard parametric amplification where the modulation occurs both in space and in time, this fundamental process requires a pure modulation in time, which makes its detection particularly challenging at optical frequencies. In this paper we experimentally demonstrate a realization of the analogue dynamical Casimir effect in the near-infrared optical regime in a dispersion-oscillating photonic crystal fibre. The experiments are based on the equivalence of the spatial modulation of the fibre core diameter to a pure temporal modulation when this is considered in the co-moving frame of the travelling pump pulse. We provide evidence of optical dynamical Casimir effect by measuring quantum correlations between the spectrally resolved photon pairs and prove their non-classical nature with photon anti-bunching.
