论文摘要
研究了非线性色散纤维中光场的哈密顿量。量子场波动是通过模拟鹰效应自发创建靠近光学事件范围的。对于光学黑洞激光器而言,考虑了最简单的模型,在该激光器中,在两个范围内形成的腔体中产生并放大了鹰辐射:黑洞和一个白孔。发现共鸣的鹰辐射源自一组离散的不稳定性和隧道。最后,将数值结果与共振和不稳定性条件进行了比较,并开发了一个现象学模型以给出清晰的物理情况。
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.
