事件视界的物理学类似于运动介质中的波的行为。在介质的局部速度超过波速的地方形成视界。我们使用微结构光纤中的超短脉冲来演示光学中人工事件视界的形成。我们观察到一个经典的光学效应：在白洞视界的光的蓝移。我们还通过理论计算表明，这样的系统能够探测视界的量子效应，特别是霍金辐射。
The physics at the event horizon resembles the behavior of waves in moving media. Horizons are formed where the local speed of the medium exceeds the wave velocity. We used ultrashort pulses in microstructured optical fibers to demonstrate the formation of an artificial event horizon in optics. We observed a classical optical effect : the blue-shifting of light at a white-hole horizon. We also showed by theoretical calculations that such a system is capable of probing the quantum effects of horizons, in particular Hawking radiation.
