光学黑洞laser的不稳定性

Instabilities in an optical black-hole laser

Juan David Rincon-Estrada, David Bermudez

摘要:

研究了非线性色散光纤中光场的哈密顿量。通过模拟霍金效应,在光学事件视界附近自发产生量子场涨落。最简单的模型被认为是一个光学黑洞激光器,其中的霍金辐射的产生和放大内形成的两个视界:一个黑洞和一个白洞的空腔。研究发现,共振霍金辐射起源于一组离散的不稳定性和视界外的隧道。最后,将数值结果与共振和不稳定条件进行了比较,并建立了一个唯象模型,给出了清晰的物理图像。

英文摘要:

The Hamiltonian of optical fields in a nonlinear dispersive fiber is studied. Quantum field fluctuations are spontaneously created close to an optical event horizon through the analog Hawking effect. The simplest model is considered for an optical black-hole laser, where the Hawking radiation is produced and amplified inside a cavity formed by two horizons: a black hole and a white hole. It is found that resonant Hawking radiation originates from a discrete set of instabilities and tunnels out of the horizons. Finally, the numerical results are compared with the resonance and instability conditions and a phenomenological model is developed to give a clear physical picture.
