Light has always been one of our most important tools to study nature and to communicate information. Optical communication is as old as mankind, and microscopes have been used for centuries to explore living organisms. However, it quickly became clear that conventional microscopes cannot resolve structures which are smaller than the wavelength of light - roughly one thousandth of a millimetre. The last three decades have seen remarkable progress in both fields through the invention of the laser, optical fibres, and new designs of optical materials. It is now possible to observe structures that are much smaller than the wavelength of light, and novel materials make optical switching possible: the path of one flash of light can be changed by switching on another light pulse. This phenomenon has been studied, e.g., for the design of an all-optical computer.

光一直是我们研究自然和传达信息的最重要工具之一。光学通信与人类一样古老，并且已经使用了几个世纪的显微镜来探索生物体。但是，很快就清楚地表明，传统的显微镜无法解析比光的波长小的结构 - 大约一千分之一毫米。在过去的三十年中，通过激光，光纤和光学材料的新设计，这两个领域都取得了显着的进步。现在可以观察到比光波长小得多的结构，并且新颖的材料使光学切换成为可能：通过打开另一个光脉冲可以改变一个光闪光的路径。已经研究了这种现象，例如，用于设计全光计算机。
