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交流信息的最重要工具之一。光通信与人类一样古老，显微镜已被用于探索生物体几个世纪。然而，人们很快就发现，传统的显微镜无法分辨比光波长（大约千分之一毫米）小的结构。在过去的三十年里，通过激光、光纤和光学材料的新设计的发明，这两个领域都取得了显著的进展。现在可以观察到比光的波长小得多的结构，新材料使光开关成为可能：一个闪光的路径可以通过打开另一个光脉冲来改变。已经研究了这种现象，例如，全光学计算机的设计。
