Final Report Summary - SPP (Surface plasmon photonics)

The SPP project aimed to significantly extend the understanding and control over surface plasmon properties by means of nanoscale engineering as well as to explore the potential for innovative photonic elements and devices. The work has been focussed on exploring the coupling between light and Surface plasmons (SPs), controlling the surface plasmon propagation as well as demonstrating surface plasmon-based devices.

The project achieved, on the one hand, in developing a nanofabrication technique which allowed sculpting metal films in order to show how a small array of holes in a metal film may be used as grating to couple light and SPs while, on the other side, developing a new computational model specifically for SP photonic structures in order to compute the SPs' coupling efficiency. Furthermore, the project achieved in demonstrating a proof-of-concept SP plasmon circuit, namely a plasmonic Waveguide ring (WR) resonator based on SP channel guides. It has been showed that surface plasmons possibly exhibit optical non-linear behaviour. Finally, the project succeeded in producing periodic, patterned structures on the scale of the wavelength of light in order to enhance the efficiency of Light-emitting diodes (LEDs) and wavelength division multiplexers.
