Plasmonics for nanophotonics
Plasmonics makes use of coupling between electromagnetic waves and free-electron excitations at the interface of good conductors.The electromagnetic field of these surface plasmons is strongly confined and enhanced at the interfaces, providing an opportunity for optical signal manipulation in ultracompact, subwavelength devices.These properties are especially suitable for development of active integrated components which can be used within purely plasmonic waveguide circuitry or incorporated into photonic, e.g., Si-based, waveguides to achieve desired functionality which is difficult to realise by other means.Going beyond conventional plasmonic materials, such as Au and Ag, new material platforms based on CMOS compatible metals such as Al and Cu, highly doped semiconductors, transparent conductive oxides and metamaterials have been developed.
In this talk I will discuss various realisations and applications of plasmonic components for enhancing performance of integrated nanophotonic devices with particular emphasis on active functionalities, such as all-optical and electro-optical modulation, nanoscale light sources, as well polarisation and dispersion management.
