Plasmonic nanodevices exploit the interaction between optics and electronics at the nanoscale. The speed of light and possible enormous bandwidth, which is used for example in optical communication via fiber connections, is combined with the possibility of metallic nanostructures to control plasmons, which are interactions between the light's electromagnetic field and conduction electrons, around metal nanostructures. In this way, the nanostructures can be used to design and control optical fields on a scale that is much smaller than the wavelength of light.
At SDU Nano Optics, we primarily do research in the field of plasmonics, where you combine optics and electronics. Plasmonic nanodevices open exciting future perspectives and can be used in a wide range of technologies such as mobile phones, computers, channel reception and the Internet.
