论文摘要
鹰辐射不太可能从真正的黑洞中测量，但可以在实验室类似物中进行测试。它的预测是由于量子力学和一般相对论，但事实证明这是更普遍的。折射率的扰动产生了由光制成的黑洞和鹰辐射的光学类似物。我们使用动手物理学讨论了光学类似物的中心和最新实验。我们强调了经典领域，负频率，“常规光学”和分散的作用。不久将讨论未来的机遇和挑战。
Hawking radiation is unlikely to be measured from a real black-hole, but can be tested in laboratory analogues. It was predicted as a consequence of quantum mechanics and general relativity, but turned out to be more universal. A refractive index perturbation produce an optical analogue of the black-hole horizon and Hawking radiation that is made of light. We discuss the central and recent experiments of the optical analogue, using hands-on physics. We stress the roles of classical fields, negative frequencies, 'regular optics' and dispersion. Opportunities and challenges ahead are shortly discussed.
