ABSTRACT

Microchips and contemporary optical data storage media are currently being produced at the limit of the conventional optical possibilities, whereas future photonics will require increased integration of photonic devices of up to 1000×1000 input and output channels on a single substrate for increased data transfer rates and for improved photolithography with feature lengths well below one wavelength.[1] Similar to electronic circuits where the transport and storage of electrons can be controlled, the concept of surface plasmon polariton (SPP)-based circuits has been proposed.[2]

Many plasmonics devices have been designed and fabricated. In this chapter, we discuss a few principal plasmonics devices.
