用光学参量振荡器模拟Casimir辐射

Analogue Casimir Radiation using an Optical Para- metric Oscillator

F. X. Dezael, A. Lambrecht

摘要:

我们建立了一个明确的类比之间的动态卡西米尔效应和光子发射的一个薄的非线性晶体内泵浦腔。这使我们能够提出一个系统的基础上,I型光学参量振荡器(OPO)模拟腔振荡在真空中的光学频率。由此产生的光子通量预计将更容易检测比机械激发的镜子。最后,我们通过比较不同的理论预测,并建议我们的实验建议可以帮助区分它们。

英文摘要:

We establish an explicit analogy between the dynamical Casimir effect and the photon emission of a thin non-linear crystal pumped inside a cavity. This allows us to propose a system based on a type-I optical parametric oscillator (OPO) to simulate a cavity oscillating in vacuum at optical frequencies. The resulting photon flux is expected to be more easily detectable than with a mechanical excitation of the mirrors. We conclude by comparing different theoretical predictions and suggest that our experimental proposal could help discriminate between them.
