Materials structured on the nanometer scale can lead to improved and sometimes surprising properties.Metals are no exception to this rule. Metal particles for instance display colours which vary with their size. The colour results from the coupling of light with the free electrons of the metal particle to form surface plasmons.On a broader level, with modern nanofabrication techniques it is possible to tailor the structure of metals and thereby to control the properties of surface plasmons opening many new possibilities from sensors to optical circuits .
The potential of surface plasmon photonics will be illustrated in some detail by our own work on the extraordinary optical properties acquired by metal films if they are simply structured with one or more apertures and periodic corrugations [2-8]. The different possibilities and challenges to create complete plasmon based photonic circuits will also be discussed [1,9,10]. Finally, the practical implications from chemistry to opto-electronics will be presented.
